Details
This command selects the type of input coupling that is used for the selected function.
When DC is selected, the instrument measures AC and DC components of the signal. When AC is
selected, the instrument only measures the AC components of the signal.
If AC coupling is selected, you can change input impedance settings, but they do not take effect until
DC coupling is selected.
Example
dmm.digitize.func = dmm.FUNC_DIGITIZE_VOLTAGE
dmm.digitize.coupling.type = dmm.COUPLING_AC
Set the digitize voltage coupling to AC.
