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 main-
tain constant amplitude as the frequency is varied.
Voltage control of frequency allows FM modulation to be intro-
duced 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 en-
ables 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
The TG120 provides switchable bi-directional variable symme-
try which enables variable duty cycle pulse waveforms and saw-
tooths to be generated.
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.
Wide range level control
The TG120 provides a main output with a maximum emf of 20V
pk-pk from a 50Wsource.
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.
An auxilliary output provides a fixed 0 to +5V level suitable for
driving both TTL and CMOS loads.
