TRIG_COUPLING | TRCP
The TRIG_COUPLING command sets the
input coupling for the selected trigger sources.
The TRIG_COUPLING? query returns the
trigger coupling of the selected source.
<trig_source>:TRIG_COUPLING
<trig_coupling>
<trig_source>:={C1,C2,C3,C4,EX,EX5}
<trig_coupling>:={AC,DC,HFREJ,LFREJ}
• AC — AC coupling block DC component
in the trigger path, removing dc offset voltage
from the trigger waveform. Use AC coupling
to get a stable edge trigger when your
waveform has a large dc offset.
• DC — DC coupling allows dc and ac
signals into the trigger path.
• HFREJ — HFREJ coupling places a low-
pass filter in the trigger path.
• LFREJ — LFREJ coupling places a high-
pass filter in the trigger path.
<trig_source>:TRIG_COUPLING?
<trig_source>:TRIG_COUPLING
<trig_coupling>
The following command sets the coupling
mode of the trigger source Channel 2 to AC.
