Measurements on Multiplexer Modules
The Keysight DAQ970A supports many common measurement functions with the multiplexer module.
With any multiplexer module installed on the rear panel, press [Module] and use the knob or the front panel
arrow keys to navigate into the desired multiplexer module.
You can configure the measurement function on the selected channel by pressing [Channel] > Measure.
Selecting Off will disable the measurement function in current selected channel. No any measurement func-
tion will be displayed in the scan list on the selected channel. Default measurement function will set to DC
voltage.
Table below shows the overview of each supported multiplexer module on the measurement function. Click
