Agilent N6781A Auxiliary Voltage Measurements

The following information only applies to Agilent Model N6781A.
The Agilent N6781A has an auxiliary voltage measurement input,
whose primary use is for battery voltage rundown measurements. It
may also be suitable for other applications including general purpose
DC voltage measurements between +/-25 VDC. The auxiliary voltage
measurement input is isolated from other commons. It has a
bandwidth of about 2 kHz. It has one input range: −25 to +25 VDC.
Auxiliary voltage measurements cannot be made along with output
voltage measurements. When the auxiliary voltage measurement
input is selected, all voltage measurement functions receive their
input from this source instead of the normal + and − sense terminals.
These functions include the front panel, SCPI measurements, Scope
View, Data Logger View, Elog, and histogram measurements.
From the front panel
To enable auxiliary voltage measurements, select Meter View, then
Properties, then select Aux Voltage.
The instrument will continuously display the auxiliary voltage
measurement on the front panel Meter View:
When the auxiliary voltage measurement terminals are left unconnected, the
front panel meter will indicate a voltage reading of approximately 1.6V. This is a
normal indication which does not affect the external voltage measurement once
the measurement terminals are connected.
From the remote interface:
