:CHANnel<n>:COUPling
Syntax
:CHANnel<n>:COUPling <coupling>
:CHANnel<n>:COUPling?
Description
Sets or queries the coupling mode of the specified channel.
Parameter
Name
Type
Range
Default
<n>
Discrete
{1|2|3|4}
——
<coupling>
Discrete
{AC|DC}
DC
Remarks
 AC: the DC components of the signal under test are blocked.
 DC: both DC and AC components of the signal under test can pass through the
channel.
Return
Format
The query returns AC or DC.
Example
:CHANnel1:COUPling AC /*Selects the AC coupling mode.*/
:CHANnel1:COUPling? /*The query returns AC.*/
