Coker drum safety for crude oil refineries

Coker Drum Safety System prevents unsafe actions by coker drum operators.
The SIS-TECH Coker Drum Safety System (CDSS) automatically inhibits the opening of valves under unsafe process conditions. In a crude oil refinery, this prevents the release of hydrocarbons and/or hydrogen sulfide to the atmosphere, or introduction of hydrocarbons to an open drum. The CDSS logic solver makes sure that an in-service drum is not opened to the atmosphere, or that an open drum is not placed in service.

Understanding the Problem
OSHA (US Department of Occupational Safety & Health) says, in Hazards of Delayed Coker Unit (DCU) Operations, “The batch portion of DCU drum switching and coke cutting operations creates unique hazards, resulting in frequent and serious accidents.” The specific hazardous operating states are listed as coker drum switching, coker drum removal, and coke cutting (hydroblasting) operations.

Each DCU has at least two coker drums, and an operator is responsible for manually lining up the coker drums and valves. Although operator procedures and training emphasize the importance of correct line-up and the hazards of deviating from approved procedures, accidents often occur. Failure to open or close valves in the correct sequence can result in the release of hot hydrocarbons and/or hydrogen sulfide gas, and can also cause a fire.

Improper line-up of coker drums has led to several serious accidents, including fatalities. Because valve line-up is manually executed, operator error is one of the leading causes of these accidents.

Total Automation Solutions (TAS), recently installed a CDSS system at a major refinery. “The use of the CDSS in conjunction with the TAS Coker Interlock System eliminated the need to install a safety programmable logic controller (PLC),” said J.R. Thompson, senior vice president at TAS. “The installation was simple and straightforward, requiring only that we clearly defined the conditions under which certain valves could be opened or closed.”

Thompson has been working with refineries and coking systems for years, and he appreciates the safety and simplicity of the CDSS. “Without a CDSS, we would have to engineer, design and program a separate safety PLC system. This is a significantly more costly solution, and requires that the refinery have staff available to support the safety PLC.”
Monitoring Operator Actions
The SIS-TECH CDSS is a safety instrumented system independent of the TAS Coker Interlock System and other plant control systems. The CDSS monitors process conditions to prevent operations from opening the wrong valve or performing operations on the wrong drum. The CDSS provides a totally independent logic solver coupled with independent process sensors to provide a stand-alone layer of protection for the coker drum.

For each Coker Drum, the CDSS monitors three process variables: overhead pressure, overhead temperature and inlet temperature. It verifies safe conditions before allowing the TAS Coker Interlock System operator to open the vent, drain, top/bottom head, blowdown, overhead to fractionator, or inlet feed valves.

The CDSS logic solver monitors process variables to detect unsafe conditions. It then removes the permissive to operate the affected valves and sounds an alarm, thus preventing the valve from opening at the wrong time.

The CDSS is suitable for use up to SIL-3. The number of inputs and voting architecture (1oo1. 1oo2, 2oo2 or 2oo3) can be adjusted for each process variable to meet any SIL or reliability requirement. The CDSS is rated for -30 to 75C operation, meets Class I Div II requirements, and can be installed in harsh refinery environment near the equipment under control.

Field installation and implementation of the CDSS logic solver costs less than half that of a safety PLC. In addition, on-going support costs are much lower as the CDSS is much simpler to maintain than a safety PLC.

Outdoor enclosures

Plastic connector housings

High-quality plastic connector housings are rugged, lightweight and cost-effective

The new Han-Eco® from Harting is a complete range of high-quality all-plastic industrial connector housings that combine ruggedness, light weight and reduced costs with versatility, safety and reliability.

Han-Eco® is the ideal solution for users who require a cost-effective, lightweight product and who do not require the full range of product features offered by Harting's established Han® B series of connector housings. The product also offers a higher contact-density/housing-size ratio than the Han® B series.

Like the Han® B standard series, the Han-Eco® series is available in sizes 6 B, 10 B, 16 B and 24 B. Depending on size, versions of the bulkhead mounting and hood with straight or angled cable exit can be supplied. The cable exits are available with metric threading.

Han-Eco® housings are made of high-performance plastic that is highly resistant to environmental stress and - in combination with the design - provides very good mechanical stability. When the connector is closed and locked, it provides IP 65 protection as defined in DIN EN 60 529. The material also meets the demanding flammability requirements of UL 94 Class V 0.

Fast, simple assembly is a key product feature, with a click-and-mate design totally eliminating the need for tools during assembly.

The Han-Eco® housing is compatible with the full range of modules from the Harting Han-Modular® series of industrial connectors. One extra module fits into the Han-Eco® housing compared to the equivalent product in the Han® B Standard series. This special feature applies to all four sizes.

A PE (protective earth) module has been developed specifically for the Han-Eco® housing to hold the protective ground conductor. Use of the PE module is optional depending on the application.

The new Harting series complies with all standards relating to user safety. All metal parts in the PE system are fully connected to the protective ground conductor. This prevents the risk of anyone touching live parts if a fault occurs. The housing is also suitable for use on machines and systems with Class II protective insulation.

To ensure a safe, compliant PE connection, the housings are not compatible with the Han® B Standard series. However, the mounting dimensions of the Han-Eco® bulkhead are identical with the mounting dimensions of the Han® B Standard series, eliminating the need to modify control cabinet side panels.

The locking lever (locking system with two transverse levers on all sizes) can be mounted on the bulkhead or the hood to suit user needs. A coupling hood is also available for cable-to-cable applications.

Gearshift indication in racing

West Surrey Racing choose Variohm cable-extension transducers for neat gearshift indicator solution
When West Surrey Racing (WSR) needed a rapid solution to improve the gearshift indicator system on its FIA World Touring Car Championship BMW 320si, they chose MTA series cable-extension transducers from motorsports sensor specialists Variohm EuroSensor. The neat solution was delivered on the same day as the initial enquiry, in time to meet the deadline for FIA race approval, and easily installed and electrically interfaced to a simple dashboard display to indicate the selected gear from the gear stick position.

The compact miniature 'stringpot sensor' from Celesco was chosen for its installation simplicity and robustness. The 35 mm diameter x 13 mm thick sensor provided the distance measurement directly from the BMW's H-pattern 5-speed gearshift mechanism without the need to ensure precision alignment, with the integral spring loaded stainless steel cable simply connected to the gear stick. The IP55 rated aluminium housed unit was supplied on an optional mounting bracket that was fixed in a slightly offset position on the car chassis to ensure each gear position returned a different position reading.

WSR chose the smaller of two MTA models with a 75 mm stroke and voltage divider (potentiometer) output powered from the car's 12 VDC supply. The high duty cycle conductive plastic potentiometer has an essentially infinite resolution and very long working life, and with a full stroke accuracy of better than ±0.4% and repeatability of ±0.02%, it provided more than adequate performance for the application.

With demanding applications in areas such as heavy construction equipment and agricultural machinery, the MTA series is well suited to the arduous environmental conditions that the BMW typically sees throughout a race.

WSR is based in Sunbury-on-Thames (GB) and in addition to its eBay-backed FIA WTCC BMW 320si race team, also competes in the British Touring Car Championship and provides R&D, CAD and engineering services throughout the motorsports industry that can accommodate anything from one-off performance prototypes to 'Limited Edition' production.

Variohm EuroSensor also supplies WSR with ride height position measurement solutions using its race proven ELPM series linear slimline linear position transducers. The compact rod-type ELPM provides stroke lengths up to 75 mm in IP67 sealed housings.

Internal & remote temp measurement

Digital monitor provides accurate internal & remote temperature measurements

Linear Technology Corporation has introduced the LTC2990, an I²C temperature and voltage monitor for 3V and 5V systems. Many emerging, low voltage systems today rely on monitoring ICs to relay parametric data used in assessing overall system health and reliability. Traditional ADC implementations require a sensor, low noise preamplifier, precise reference and some type of digital interface, resulting in a complex monitoring scheme prone to inaccuracies if not carefully designed. This is a highly integrated monitoring solution that incorporates a 14-bit ADC, a 10ppm/°C voltage reference and I2C digital interface to provide submillivolt voltage resolution, as well as +1°C accuracy internally and +0.5°C accuracy remotely when making temperature measurements. The LTC2990 provides a configurable, yet simple solution for monitoring temperature and voltage without compromising accuracy on any parameter.

The LTC2990 caters to a wide variety of applications including supply voltage monitoring and remote diode temperature measurement, particularly in industrial or computing systems where thermal management is crucial for maximizing performance. The device enables configuration of four single-ended voltage inputs to measure any combination of internal temperature, remote temperature, remote voltage and internal VCC for single or repeated measurements. When making differential measurements of diode or transistor voltages to calculate temperature, the LTC2990 allows for cancellation of error due to sensor series resistance. Its accuracy is the result of the averaging 14-bit ADC, while the number of supporting components and area required is minimized thanks to the internal 10ppm voltage reference. In addition, the I2C serial interface enables easy configuration and read back of the device's control, status and data registers, with support of up to 400kbit/s in I2C fast mode.

The LTC2990 is offered in commercial and industrial versions, supporting operating temperature ranges from 0°C to 70°C and -40°C to 85°C, respectively. The LTC2990 is available today in a small RoHS compliant, 10-lead MSOP package.

LIMS in Northern Ireland

Thermo Fisher Scientific Implements Enterprise-Level LIMS for Northern Ireland Water

Thermo Fisher Scientific has announced that Northern Ireland Water (NI Water), the sole provider of water and sewerage services in Northern Ireland, has standardized on Thermo Scientific SampleManager LIMS (laboratory information management system) across its laboratories as part of its continuous focus on improving sample management and maintaining the highest quality water. SampleManager LIMS is used to manage more than 150,000 samples per year taken from reservoirs, water treatment works and directly from the taps in consumers' homes. NI Water's state-of-the-art laboratories carry out the necessary testing to ensure that drinking water is safe for consumption and meets all regulatory and quality standards.

Standardizing on SampleManager LIMS across its laboratories allows NI Water to maintain the highest levels of testing and consistency in results. To enhance the quality of the test methods and to reduce time associated with collecting and logging field samples, NI Water has integrated a new handheld remote sampler with SampleManager LIMS. This allows field samples to be taken, results recorded and input directly into the LIMS, saving time, ensuring the quality of the sample at log-in, and reducing manual transcription errors as well as providing a secure record of sampler locations.

Remote Sampler, developed by CSols, is already in pilot usage with customers across Europe and in British-based water companies, who are using Remote Sampler with existing SampleManager LIMS installations. The introduction of Remote Sampler at NI Water extends the use of SampleManager LIMS to field applications, thus allowing more samples to be processed by in-the-field sampling. Because Remote Sampler reduces the time necessary to collect and log-in a sample, it enables more efficient use of laboratory resources, as well as consistent compliance with various regulatory requirements for documented processes, such as those defined by the Drinking Water Inspectorate (DWI) for the Water Industry.

"We have introduced Remote Sampler in the field for all our water quality samplers. Remote Sampler runs on rugged handheld computers and integrates seamlessly with Thermo Scientific SampleManager LIMS. The use of Remote Sampler allows us to ensure that all samples taken in the field are accurately recorded, taken where they are claimed to be, and inputted into the LIMS at source. This saves time and facilitates data management," said Gareth Maxwell, LIMS and Compliance Reporting Manager for NI Water. "With SampleManager LIMS in place and our investment in remote sampling, NI Water is setting the benchmark in the future of water testing in Europe. This solution puts NI Water in the leading edge of extracting real benefits from our quality testing programme. NI Water will have better sampling audits than most other UK water utilities currently."

"We're delighted with the working relationship that we have with Gareth and the rest of the staff at Northern Ireland Water. It has enabled us to focus on exactly what is required to make our sampling software work effectively in a busy routine environment which is tightly regulated," said Dr. Phil Goddard, CEO of CSols. "Integration with SampleManager LIMS has proved to be straightforward and robust."

NI Water is a Government Owned Company (GoCo) set up in April 2007 to provide the water and sewerage services in Northern Ireland. It supplies 625 million liters of clean water every day for nearly 1.7 million people and treats 134 million m3 of wastewater each year. NI Water has equipped its laboratories with the technologies and infrastructure that allow it to deliver the highest quality water which consistently meets all regulatory and quality standards for consumption. SampleManager LIMS integrated with Remote Sampler has improved the efficiency and security of data entry as samples are taken in the various field locations, and greatly assisted sample identification and tracking. As all samples are now recorded on a single electronic database, the integrated solution has provided NI Water with a means to retrieve and report data in a way that would not have been previously possible, while also ensuring the integrity of the field samples at log-in.

"The integration of the Remote Sampler with SampleManager LIMS illustrates the broad partnership opportunities inherent in any collaborative relationship with Thermo Fisher Scientific," says Dave Champagne, vp and general manager, Thermo Fisher Scientific - Informatics. "Thermo Fisher's long standing partnership with CSols enabled this solution to be delivered to NI Water, a solution which now serves as a template for other water agencies or public service companies around the world. And the configurability of SampleManager LIMS, allowing for workflow customization in any industry setting, as well as its ability to be easily integrated with any kind of laboratory instrumentation or ERP system, further enabled this new Remote Sampler solution to be realized. The ultimate benefits belong to NI Water and other companies at the forefront of solving pressing industry challenges."

Electric car battery research​

Project will investigate turning used electric car batteries into energy storage devices
ABB and General Motors have signed a non-exclusive memorandum of understanding to cooperate on a research and development project that will investigate uses for electric vehicle batteries once their useful life in the vehicle is over.

The project will examine the potential of reusing spent lithium-ion battery packs from GM’s electric car, the Chevrolet Volt, as a means of providing cost-effective energy storage capacity, which will improve the efficiency of electrical systems as they evolve into smart grids.

“Future smart grids will incorporate a larger proportion of renewable energy sources and will need to supply a vast e-mobility infrastructure – both of which require a wide range of energy storage solutions,” said Bazmi Husain, head of ABB’s smart grids initiative. “We are excited to explore the possibility of employing electric car batteries in a second use that could help build needed storage capacity and provide far-reaching economic and environmental benefits.”

According to GM, the Volt’s battery will still have significant capacity to store electrical energy, even after its automotive life.

"That’s why we’re joining forces with ABB to find ways to make the Volt batteries provide environmental benefits that stretch beyond the highway,” said Micky Bly, Executive Director of Electrical and Hybrid Systems, who announced the partnership at the EV Battery Tech conference in Troy, Michigan. “Our relationship with ABB will help develop solutions that optimize the full lifecycle of the Volt battery.”

Economical grid storage is often identified as a key “enabler” technology of smart grids that will drive the wider use of a variety of applications, including:
    managing the intermittency of wind and solar resources
    mitigating spikes in electricity demand
    providing backup power
    allowing cheaper off-peak power to be used during peak periods
ABB is currently at work on more than 20 projects around the world examining all aspects of the smart grid, from energy storage to network management, metering and communication, distribution automation and home automation systems.

Keeping trains in train!

New standards in Rail Traction are preparing the sector for more widespread trans-European, cross-border train operation, imposing stringent requirements in energy monitoring. Anticipating these new demands, transducer specialist LEM has created a measurement technology that enables unprecedented levels of accuracy in on-board monitoring of train power consumption.

The matched and optimised devices comprise transducers for current and voltage, and a new energy meter. All three units provide levels of accuracy not previously seen in the sector, and come with the specific certification recognised in the electric rail traction industry. Used together, they enable designers to meet or exceed existing and planned specifications: they also offer the same levels of accuracy to system designers working in other areas of high-power electrical supply.

Current, in the high-accuracy power transducer suite, is monitored by new introductions to LEM’s ITC 4000 or ITC 2000/1000 ranges. Certified to Class 0.5R, the ITC 4000 employs an advanced closed-loop (compensated) current measurement design based on the Fluxgate principle. Nominally rated at 4000A, the ITC 4000 will measure +/-6000A, consuming less than 80 mA (at zero primary current) to under +/-340 mA (at 4000A primary current) from a supply voltage of +/-24V to its measurement (secondary) circuit.

Fluxgate technology is noted for its high levels of both accuracy and linearity; the ITC 4000’s linearity error is under 0.05%. The device’s offset current is less than +/- 10μA and it also exhibits extremely very low temperature drift. The ITC 4000 operates over –40 to +85 deg oC, and meets or exceeds all relevant standards for safety and operating environment.

For voltage measurement to the same standards or precision, LEM offers a development of its DV series voltage transducer that spans 1200-4200V RMS. Introduced with an accuracy performance of Class 1, further development has taken the DV Series to Class 0.75 accuracy. The DV offers (as an active device) current consumption of 19-23 mA, measurement frequency bandwidth of 12 kHz, and an insulation voltage of 18.5 kV.

A more compact device than any competing transducer, The DV series measures just
134 x 54.22 x 147.25 mm; like its current-measurement transducer counterpart, it meets all of the requirements of the rail industry in terms of EMC performance, partial discharge extinction voltage and safety, while featuring low weight, and flexible mechanical mounting and electrical output characteristics.

Completing the measurement technology package is LEM’s EM4T II single-phase energy meter, also rated to Class 0.5R accuracy: this form of accuracy specification is according to the proposed EN 50463 standard that will unify measurement practices for trans-border train operation across Europe. The EM4T II is a four-channel device that records data such as load profile, and train data and location (from GPS inputs) at regular intervals. Used in conjunction with the capabilities of the ITC 4000 current transducer, the EM4T II accurately logs bi-directional power flow, enabling accurate monitoring of energy usage even under regenerative braking.

Fit-and-forget protection for low-pressure systems

A versatile new pressure relief valve for low pressure instrumentation applications up to 400 PSI (27.6 bar) has been launched by the Instrumentation Products Division of Parker Hannifin, the global leader in motion and control technologies.

A versatile new pressure relief valve for low pressure instrumentation applications has been launched by Parker Hannifin.CE marked and certified to the highest Category-IV level of the Pressure Equipment Directive (PED) the new HPRV valve is supplied pre-set to any of six pressure ranges from 10 to 400 PSI (0.7 to 27.6 bar). The chosen cracking pressure is laser etched onto the valve body at the factory. Another variant of this relief valve design is available for higher pressure applications.

The new HPRV valve provides a simple 'fit and forget' solution for building reliable safety, environmental and/or equipment protection into a wide variety of process and laboratory instrumentation applications - one that needs no testing or calibration by the end user.

Unlike some competitive products, Parker supplies each HPRV low pressure valve as a complete item including the spring that determines the cracking pressure, under a single order number to simplify purchasing. The valve is 100% PED certified, and requires no additional paperwork or approvals to use the product. Parker has additionally set up its manufacturing and assembly process to ensure short lead-times.

The valve has a 5.2 mm (0.203 inch) orifice. As standard, it comes with either twin-ferrule A-LOK or single-ferrule CPI compression tube fitting ends, eliminating threaded connections and the potential problems that are associated with using thread sealants such as PTFE tape. Other types of end connection may be specified to suit the installation.

The valve's outlet port can release over-pressures to atmosphere, or be configured to duct media to a safe place. The cracking pressure is determined by one of six factory-fitted springs. These provide a choice of six cracking pressure ranges: 10-25, 25-50, 50-100,100-150,150-225 or 225-400 PSI (0.7-1.7, 1.7-3.4, 3.4-6.9, 6.9-10.3, 10.3-15.5 or 15.5-27.6 bar). A locking wire may be fitted to secure the chosen pressure setting and guard against tampering.

O-ring seals adapt the HPRV valve for different types of media, and operating temperatures from -57 to 204 degrees C (-70 to +400 degrees F). Five choices of material are available: fluorocarbon rubber and nitrile rubber for general-purpose use, ethylene propylene or neoprene rubber for compatibility with a wider range of chemicals, or highly fluorinated fluorocarbon rubber which is compatible with a very wide range of chemicals.

Charles Harris, Business Development Manager for Parker Hannifin, comments: "The introduction of these low pressure options rounds out Parker's range of relief valves for process instrumentation applications, providing users with the means to select optimised and accurate protection for pressure-containing systems operating from 10 to 6000 PSI. The European Directive approval also gives us a distinct advantage over many of our key competitors."

OPC Firewall shipping

Earlier this month we reported on Byres Security's Tofino OPC Enforcer, a rather revolutionary firewall technology. This is now available and shipping. This new module is designed specifically to secure industrial systems using OPC Classic.

OPC Classic (i.e. all OPC variations other than OPC-UA) is the world’s most widely used industrial integration protocol. Unfortunately, it is also famous for being very difficult to secure.

The Tofino OPC Enforcer radically changes the OPC security landscape because:
  • It is the first ever industrial firewall for managing OPC traffic. Unlike other firewalls, this product inspects, tracks and secures every connection made by an OPC application, opening only the exact TCP port required for a connection between an OPC client and server.
  • It is implemented without requiring any changes to the control system. The Tofino hardware is simply installed into the live network and configured using a drag and drop editor to select permitted clients and servers. Once installed, network security is assured, with all OPC traffic managed behind the scenes.
They have also published an OPC Feature Page, which is a hub of information on OPC and security, and includes a link to download a new White Paper titled “Securing Your OPC Classic Control System” written by me and Thomas J. Burke, the President of the OPC Foundation.

Smallest strain sensor with highest resolution

With the strain sensor DSRT, Baumer offers a sensor for indirect force measurement which can be used in the packaging industry, engineering, wind energy plants and many other industrial applications. The DSRT is the smallest strain sensor with the highest resolution (0.01 µε) available on the market. It is offered with measuring ranges from 0…100 µε up to 0…750 µε (micro strain: µm/m).

The strain sensor is suitable for all static and dynamic applications and can be used wherever strains are expected, e. g. for process control in presses and punching machines, for monitoring blade deflection in wind energy plants, or for sheet metal forming applications in the packaging technology. The indirect force measurement enables the control and traceable documentation of forces in the process. It also guarantees the repeatability of the individual processes, thus ensuring consistent quality.

The DSRT is available with the measuring ranges ±100, ±250, ±500, and ±750 µε. It has an integrated low-noise bridge amplifier with an analogue signal path and a high cut-off frequency (1 kHz). The available output signals are analogue current or voltage signals (4…20 mA, ±10 VDC, mV/V) and a CANopen interface. The sensor offers high reliability, long-term stability, overload protection, and repeatability. The device conforms to protection class IP67.

Since the strain sensor is screwed on to the strain-stressed parts of the machine, it offers many advantages compared to glued strain gauges (SG): it is reusable, can be mounted much faster and easier, is replaceable without recalibration, and offers very high application security. Low mechanical setting and warming up enable a fast start-up. Compared to force sensors, the DSRT allows cost-efficient measurement especially of high forces. The device is 80 mm long, 26 mm wide, and 17 mm high.

In-vehicle communication

The IEC (International Electrotechnical Commission) promulgates the IEC 61375 series train communication networks (TCN).

Besides other communication technologies, CANopen has been selected as in-vehicle or train consist network (IEC 61375-3-3). This standard specifies additions to the generic CANopen application layer standard (EN 50325-4).

This is based on the CAN data link layer as specified in ISO 11898-1. CAN was originally developed for car in-vehicle networking. Nowadays, more than 600 millions of CAN chips are used per year.

CANopen might be called a hidden technology, because it is mainly used in embedded control applications. Typical examples are diesel engine or door or lightning control systems. CANopen is used especially in local and urban trains, in metros and trams. But increasingly it is used also in sub-systems for long-distance and cargo trains. In particular, the robustness of the CAN physical layer, the reliability of the CAN data link layer, the flexibility of the CANopen application layer, and the high-level interoperability of the CANopen profiles makes this technology so suitable for rail vehicle applications. Members of the CAN in Automation (CiA) nonprofit association develop dedicated CANopen profiles for trains. Several sets of profiles have been released, e.g. for diesel engine systems (CiA 423 series).

Validated for Wi-Fi

Anritsu's MT8860C WLAN Test Set is now validated as part of the overall test system for Wi-Fi CWG (Converged Wireless Group) Certification Testing. The decision taken by the Wi-Fi Alliance means that the MT8860C can be used by any top-tier independent laboratory that has been authorized by the CTIA and Wi-Fi Alliance to perform RF performance evaluation of Wi-Fi Mobile Converged Devices. The testing, which is mandatory for any Wi-Fi mobile converged device for the North American market, provides network operators and handset vendors with a consistent method of evaluating and comparing the RF performance of devices that incorporate both Wi-Fi and cellular technologies.

Testing is performed according to the "Test Plan for RF Performance Evaluation of Wi-Fi® Mobile Converged Devices," as a new firmware version (11.2) has been released for the MT8860C that supports the test methodology defined. The test plan includes a comprehensive set of over-the-air (OTA) measurements that are taken in a 360° environment to create "real-world" conditions. Total Radiated Power (TRP) measurements provide information about the reach of the Wi-Fi signal sent by a converged device, while Total Isotropic Sensitivity (TIS) measurements indicate how well a converged device is able to detect an incoming Wi-Fi signal.

OTA measurements require specialized test systems. As part of the MT8860C validation process, a joint development program was established between Anritsu and ETS-Lindgren. As part of the program, ETS-Lindgren developed a new MT8860C instrument driver for use with its EMQuestTM EMQ-100 Data Acquisition and Analysis Software. This software not only controls the measurement equipment (MT8860C), but is capable of positioning the antenna relative to the converged device under test and post processing the measurement data to produce the required 2-D and 3-D antenna patterns.

Validation was achieved after the MT8860C had successfully passed a set of acceptance tests defined by the Wi-Fi Alliance. Based on these tests, the Wi-Fi Alliance concluded that the MT8860C performance is within the required measurement uncertainty for conducted Tx, Rx, and OTA TRP, TIS tests. In addition, the Wi-Fi Alliance was able to confirm that the linearity of the MT8860C is well behaved across all the UNII bands and provides consistent measurement results for 802.11a converged devices.
