4.19.7 :COUPling AC|DC
[:SENSe[1]]:CURRent:AC:COUPling AC|DC Specify coupling for ACI
[:SENSe[1]]:VOLTage:AC:COUPling AC|DC Specify coupling for ACV
[:SENSe[1]]:FREQuency:COUPling AC|DC Specify coupling for FREQ
Parameters AC AC coupling
DC AC+DC coupling
Formats :curr:ac:coup ac :volt:ac:coup ac :freq:coup ac
:curr:ac:coup dc:volt:ac:coup dc:freq:coup dc
Defaults Power-up Saved power-on setup
*RST AC
:SYSTem:PRESet AC
Query :COUPling? Query currently programmed coupling
Short-form format: :curr:ac:coup?
:volt:ac:coup?
:freq:coup?
Response message: AC or DC
Description This command is used to select the input coupling for the AC, ACV and the FREQ functions. When AC
coupling is selected, a DC blocking capacitor is placed in series with the AC measurement circuit. This
removes the DC component from the measurement.
