dmm.digitize.coupling.acfrequency
This attribute allows you to optimize the amplitude to compensate for signal loss across the coupling capacitor
when AC coupling is selected.

Details
This command is only used when the digitize coupling type is set to AC.
For example, if you are measuring a 50 Hz signal, you could set this to 50 Hz to compensate for
voltage drop across the coupling capacitor.
Example
dmm.digitize.func = dmm.FUNC_DIGITIZE_VOLTAGE
dmm.digitize.coupling.type = dmm.COUPLING_AC
dmm.digitize.coupling.acfrequency = 50
Set the digitize function to voltage.
Set the coupling type to AC.
Set the frequency to 500 Hz.
