Coupling
PRx:COUPLING, PRx:CPL
Command/query
Description The PRx:COUPLING command sets the input coupling for the + and –
inputs of the differential amplifier. The valid arguments are AC, Ground and
DC.
The PRx:COUPLING? query returns the input coupling setting of the + and
– inputs of the differential amplifier connected to the specified channel.
The – input coupling is ignored when PVG Mode is set to V
COMP
. Likewise,
the – input coupling argument is not returned from a query when PVG
Mode is set to V
COMP
.
Command Syntax :CouPLing<+coupling>|,<–coupling}|
:={PR1, PR2, PR3, PR4}
<+coupling>:={AC, DC or GND}
<–coupling>:={AC, DC or GND} (ignored when PVG Mode is set to
V
COMP
)
Query Syntax :CouPLing?
Response Format :CPL<+coupling>,<–coupling>
Example The following command sets the + input coupling to DC and the – input
coupling to ground for the differential amplifier connected to channel 2.
