AC Gain control
Sets the gain of the signal channel amplifier according to the following table:-
n AC Gain
0 0 dB
1 6 dB
2 14 dB
3 20 dB
4 26 dB
5 34 dB
6 40 dB
7 46 dB
8 54 dB
9 60 dB
10 66 dB
Read auxiliary analog-to-digital inputs
The response for ADC1 to ADC4 (n = 1 to 4 respectively) in fixed point mode is an
integer in the range -12000 to +12000, corresponding to voltages from -12.000 V to
+12.000 V, and in floating point mode it is in volts.
Auto Default
The ADF command performs an auto-default operation according to the following
table:
n Significance
0 All instrument settings are returned to their factory default values
1 All instrument settings, with the exception of the communications settings, are
returned to their factory default values
NOTE: If the ADF 0 command is used when the communications settings are at
values other than their default settings, then communication will be lost.
Auto-Phase (auto quadrature null)
Perform an Auto-Sensitivity operation
Perform an Auto-Measure operation
Oscillator amplitude sweep start amplitude
Sets the start amplitude for a subsequent sweep of the internal oscillator amplitude, in
the range 0 to 1.000 V
In fixed point mode, n is in millivolts rms, and in floating point mode n is in volts
rms
