INPut<n>:COUPling
Syntax: INPut<n>:COUPling AC | DC | GROund
<n>
Query form: INPut<n>:COUPling?
<n>
Response: AC | DC | GRO
Description:
Selects the vertical input coupling of a specified <n> input channel. If AC is
specified, the DC offset value is excluded. If DC is specified, the DC offset value
is included. If GROund is specified, the AC value is grounded (zeroed).
After a RST command, the coupling is DC.
*
Restrictions:
For the PM33x0B CombiScope instruments channel 3 is not applicable, and the
input coupling of channel 4 (EXT TRIG) can only be set to AC or DC.
