MAUI Oscilloscopes Remote Control and Automation Manual
COUPLING, CPL
Description
The COUPLING command selects the coupling mode of the specified input.
The COUPLING? query returns the coupling mode of the specified channel.
Command Syntax
<channel>:COUPLING <coupling>
<channel>:= <C1 to Cn, EX, EX10, ETM10>
<coupling>:= {A1M, D1M, D50, GND}
The selected coupling value must be one that is available on the oscilloscope. Not all values are supported
by all instruments.
A1M and D1M attenuation pertains only to instruments with a probe connected.
Query Syntax
<channel>:COUPLING?
Response Format
<channel>:COUPLING <coupling>
<coupling>:= {A1M, D1M, D50, GND, OVL}
OVL is returned in the event of signal overload while in DC 50 Ω coupling. In this condition, the oscilloscope
will disconnect the input.
Example (GPIB)
The following instruction sets the coupling of C2 to 50 Ω DC:
CMD$="C2:CPL D50": CALL IBWRT(SCOPE%,CMD$)
The following instruction sets of the coupling of the EXT input to DC 1 Mohm:
CMD$="EX:CPL D1M": CALL IBWRT(SCOPE%,CMD$)
