USER'S MANUAL GF-941

1. GENERAL

1.1 Description

The GF-941 Function Generator covers a wide frequency range, from 0.2 Hz to 20
MHz. It is a very adaptable device through the several variation means of the three main
waveforms it generates: sine, triangular and square.
Time symmetry can be changed and overlapping a variable continuous voltage as
well.
Two generators are combined into one. One of them is used as an auxiliary
generator for both AM and FM modulation functions, sweep function or for triggering the
main generator, supplying a given number of selected waveform periods, or burst function,
in a recurrent way. Both frequency and the auxiliary waveform can be selected at the
panel. The main generator is provided with a frequency indicator, to lessen reading errors.
