OPERATION
Operation as a Voltage Controiled Generator
No preparation for operation is required beyond com-
pletion of the initial installation previously stated in
this section. It is recommended that a one-half hour
warm-up period be allowed for the associated equip-
ment to reach a stabilized operating temperature and
for the Model 132 to attain stated accuracies.
The VCG input connector can be used to externally
control the frequency of the generator. If a positive
voltage is applied to the VCG input terminal, the
frequency will increase from the dial setting, A nega-
tive voltage will cause the frequency to decrease from
the dial setting. The VCG range of the Model 132 is
1000:1.

A positive or negative dc offset may be applied
to the waveform by setting the DC OFFSET

VCG input requires 0 to
volts for
operation over full-scale range, but can
withstand many times maximum input.

For frequency modulation with ac input, set
dial for center frequency.
