Auto Default Function

The Auto-Default computer command ADF 1 sets the model 7124's controls and
output displays as follows:-
Main Display
Displays the AC Gain, full-scale sensitivity, reference phase, time constant,
reference phase and oscillator frequency controls on the left-hand side. On the right-
hand side, the display mode is set to two bar-graphs and two large digital displays,
showing signal magnitude as a percentage of full-scale, X channel and Y channel
outputs in volts and signal phase in degrees.
The twelve basic instrument controls are set to the following values:-
Full-scale sensitivity
AC Gain
Time constant
Oscillator frequency
RCU Oscillator amplitude
AUX DAC1 output
AUX DAC2 output
AUX DAC3 output
AUX DAC4 output
Ref Phase
Phase quadrant
X channel output offset
Y channel output offset
