Dmm.digitize.coupling.acfrequency - Keithley DMM7510 Reference Manual

Section 8: TSP command reference

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.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
value = dmm.digitize.coupling.acfrequency
dmm.digitize.coupling.acfrequency = value
value
Functions
dmm.FUNC_DC_VOLTAGE
dmm.FUNC_AC_VOLTAGE
dmm.FUNC_DC_CURRENT
dmm.FUNC_AC_CURRENT
dmm.FUNC_TEMPERATURE
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
