Multiplexer modules: Measurements
The Keysight DAQ970A/DAQ973A supports many common measurement functions with the multiplexer module.
You can configure the measurement function on the selected channel by pressing [Channel] > Measure.
In Scan data acquisition mode, selecting Off will disable the measurement function in current selected channel. No
measurement function will be displayed in the scan list on the selected channel. The default measurement function
will set to DCV (DC Voltage).
In DMM Digitize data acquisition mode, by default the first suitable channel will automatically configured for DMM
Digitize and it will be assigned a measurement function (DCV by default). You may switch to another available
channel on the plug-in module and configure it for DMM Digitize operation instead. In contrast to Scan mode, there
is no Off function available because DMM Digitize can only utilize a single configured channel for its digitizing
operation. Therefore, the selected channel's measurement function must always be enabled.
Table below shows the overview of each supported multiplexer module on the measurement function. Click on each
link to see the details of each configuration step.
