Basic analog function generator offers high waveform quality

Aim-TTi has extended their TG300 series of low cost analog function generators by adding a model with vernier-dial setting of frequency. The TG310 is the most basic generator in the range and lacks the digital display of frequency and level that is included on other models.

The generator can produce sine, square, triangle, pulse and ramp waveforms from 0.03Hz up to 3MHz. Variable bi-directional symmetry with constant frequency is provided over a ten to one range. An external sweep input allows the frequency on each range to be varied by at least 1000:1.

The TG310 provides a main output with a maximum emf of 20V pk-pk from a 50 Ohms or 600 Ohms source. An amplitude vernier with a range of 20dB is combined with two switched attenuators of -20dB and -40dB to provide levels down to 2mV pk-pk un-terminated.
Unlike some other lower cost function generators, high waveform quality is maintained down to very low levels with minimal noise and waveform aberrations.

Variable DC offset of +/-10V is available via a centre detent control. An auxiliary output provides a fixed 0V to +5V level suitable for driving both TTL and CMOS loads
