TG120 Low-cost 20MHz function generator An essential instrument The function generator is one of the most versatile instruments available. It can generate a variety of precision waveshapes over a range of frequencies from mHz to MHz. It can provide a wide range of controlled amplitudes from a low impedance source and maintain constant amplitude as the frequency is varied. Voltage control of frequency allows FM modulation to be introduced or can provide a swept frequency source for such tasks as frequency response testing. 20MHz from a low-cost generator Most lower cost function generators use a technology which enables them to operate up to no more than 2MHz. The TG120 utilises an alternative technology which retains its waveform quality right up to 20MHz. Variable symmetry for pulse and ramp waveforms Technical Specifications FREQUENCY Frequency Range: Vernier Range: Vernier Accuracy: Input Impedance: Sweep Range: Input Sensitivity: Max. Input Voltage: Max. Slew Rate of sweep voltage: SINE Distortion: Amplitude Flatness: Sweep mode operation (external) The TG120 can be operated in sweep mode by connecting an external sweep voltage.

The TG120 provides a main output with a maximum emf of 20V pk-pk from a 50W source. An amplitude vernier with a range of 26dB is combined with two -20dB switched attenuators to provide levels down to 10mV pkpk. Variable DC offset of 10V is available via a centre detent control. An auxilliary output provides a fixed 0 to +5V level suitable for driving both TTL and CMOS loads. 0.2Hz to 20MHz in 8 overlapping decade ranges with fine adjustment by a vernier. >10:1 on each range.
