Connecting the Auxiliary Voltage Measurement Input
This information only applies to Keysight Models N6781A and N6785A.
The auxiliary voltage measurement input is located on the rear panel of
the Keysight N6781A and N6785A. It is primarily used for battery voltage
rundown measurements, but it is also suitable for general purpose DC
measurements.
The auxiliary voltage measurement input is isolated from other
commons. It has a bandwidth of about 2 kHz. It has one input range: −20
to +20 VDC.
As shown in the following figure, auxiliary voltage measurements cannot
be made on test points that are at a greater potential than ±60 VDC from
ground. Refer to chapter 4 under “Making Measurements” for more
information.
When using the auxiliary voltage measurement input, no output terminal
or measurement input terminal may be more than ± 60 VDC from any
other terminal and chassis ground.
