ACQUISITION
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}
<coupling> : = {A1M, A50, D1M, D50, GND}
The A of the <coupling> is alternating current. The
D of the <coupling> is direct current.1M and 50 is
the impedance of input. Some series (CML)
couldn‘t have the set of input impedance.
Note:
The options of <coupling> vary with models. If
your oscilloscope is an SPO model, the options are
{A1M, A50, D1M, D50, GND}, otherwise the
options are {A1M, D1M, GND}.
QUERY SYNTAX
<channel>: CouPLing?
RESPONSE FORMAT
