Syntax
CH<x>:COUPling { AC | DC | GND }
CH<x>:COUPling?
Arguments
AC sets the specified oscilloscope channel to A C coupling.
DC sets the specified oscilloscope channel to D C coupling.
GND sets the specified oscilloscope channel to ground. Only a flat ground-level
waveform is displayed.
Examples
CH1:COUPLING AC establishes AC coupling on channel 1.
CH2:COUPLING? might return DC. Indicating that channel 2 is set to DC coupling.
CH<x>:CURRENTPRObe
Sets or queries the scale factor of the specified channel for c urrent probes. The
value of <x> can vary from 1 through 4 for 4-channel instruments or 1 through
2 for 2-channel instruments.
You can issue this command when CH<x>:YUNit <QString> is set to V. However,
this command only affects the readouts when CH<x>:YUNit <QString> is set
to A.
