COUPLING, CPL
Command/Query
DESCRIPTION
The COUPLING command selects the coupling mode of the
specified input channel.
The COUPLING? query returns the coupling mode of the
specified channel.
COMMAND SYNTAX
<channel> : CouPLing <coupling>
<channel> : = {C1, C2, C3, C4, EX, EX10,ETM10}
<coupling> : = {A1M*, D1M*, D50, GND}
QUERY SYNTAX
<channel> : CouPLing?
RESPONSE FORMAT
<channel> : CouPLing <coupling>
<coupling> : = {A1M, D1M, D50, GND, OVL}
<coupling> : OVL is returned in the event of signal overload while in
DC 50 Ω coupling. In this condition, the oscilloscope will disconnect
the input.
AVAILABILITY <channel> : = {C3, C4} only on four-channel instruments.
* attenuation pertains only to instruments with a probe connected
EXAMPLE (GPIB)
The following instruction sets the coupling of Channel 2 to 50 Ω DC:
