Most lower cost function generators use a technology which enables them to operate up to no more than 2MHz.
The TG120 utilizes an alternative technology which retains its waveform quality right up to 20MHz.
Sweep mode operation (external) The TG120 can be operated in sweep mode by connecting an external sweep voltage. A sweep range of at least 20:1 can be achieved.
Variable symmetry for pulse and ramp waveforms
The TG120 provides switchable bi-directional variable symmetry which enables variable duty cycle pulse waveforms and sawtooths to be generated.
Wide range level control The TG120 provides a main output with a maximum emf of 20V pk-pk from a 50 source.
An amplitude vernier with a range of 26dB is combined with two -20dB switched attenuators to provide levels down to 10mV pk-pk. Variable DC offset of ±10V is available via a centre detent control.
Auxiliary Output
An auxiliary output provides a fixed 0 to +5V level suitable for driving both TTL and CMOS loads.
