Analog Output - Keysight B2980B Series User Manual

Analog Output

The B2980 has the Analog Out terminal on the rear panel. The Analog Out
terminal always outputs a non-inverse voltage within 2 V range, proportional to
the present measurement result for the full scale value of the measurement range.
Since this output is not calibrated, the full scale of this output voltage depends on
the measurement mode and the used measurement range. And also, it has
maximum 10 % gain error.
The following formula is carried if the Analog Out output voltage (AOut) is 0 V
when the input signal level is 0 V.
AOut (V) = Input/Range  AOutGain  2
Input: Input level
Range: Full scale value of measurement range
AOutGain: Gain for the Analog Out voltage as shown in
