Chapter 5, WEB CONTROL PANEL OPERATION
5-34
Magnitude% (2.5V fs)
In this setting the corresponding DAC connector on the rear panel of the
instrument outputs a voltage related to the MAG1%fs display as follows:-
MAG%fs DAC Voltage
+300 7.5 V
+100 2.5 V
0 0.0 V
Phase (+9 V = +180°)
In this setting the corresponding DAC connector on the rear panel of the
instrument outputs a voltage related to the Phase 1 display as follows:-
PHA deg DAC Voltage
+180 9.0 V
+90 4.5 V
0 0.0 V
-90 -4.5 V
-180 -9.0 V
Noise (2.5V fs)
When set to Noise the corresponding DAC connector on the rear panel of the
instrument outputs a voltage related to the Noise%fs display as follows:-
Noise%fs DAC Voltage
+300 7.5 V
+100 2.5 V
0 0.0 V
NOTE: When Noise is selected as an output, the noise measurement mode
(Main Controls panel) must be ON.
Ratio (10.X%/ADC1)
When set to Ratio the corresponding DAC connector on the rear panel of the
instrument outputs a voltage related to the result of the Ratio calculation, which
is defined as follows:-
10 X output
RATIO
ADC1 Input





where X output is the X channel output as a percentage of the full-scale
sensitivity and ADC 1 is the voltage (expressed in volts) applied to the ADC 1
input connector on the rear panel of the instrument. Hence, for example, if the
instrument were measuring a 100 mV signal when set to the 500 mV sensitivity
setting, the X channel output were maximized and a 1 V signal were applied to
the ADC1 input, then the value of RATIO would be:-
0.1

The relationship between the voltage at the DAC connector and the RATIO
