Remote Control (SCPI) Commands
High-Speed Power Meter 143
Specific Commands
TRIGger:SEQuence:LEVel?
Description This query returns the power level of the trigger condition to be
met to start an acquisition, in dBm or W depending on the
currently selected unit.
Syntax TRIG:SEQ:LEV?
Response The trigger power level in the “-90.000” to “+90.000” (dBm) or
“+999.9999E+99” (W) format depending on the currently
selected unit.
Example TRIG:SEQ:LEV?
See also TRIG:SEQ:LEV, TRIG:SEQ:SLOP, TRIG:SEQ:SLOP?,
TRIG:SEQ:SOUR, TRIG:SEQ:SOUR?, TRIG:SEQ:STAT, and
TRIG:SEQ:STAT?
TRIGger:SEQuence:SLOPe
Description This command sets the edge status of the trigger condition, i.e.,
defines whether acquisitions will be triggered by positive or
negative TTL voltage transitions. If this command is sent while
an acquisition is in progress, the “Acquisition already running”
error message will be raised.
Syntax TRIG:SEQ:SLOP:POS
Parameters The parameter defines the trigger condition status:
“NEGATIVE”-falling-edge trigger
“POSITIVE”-rising-edge trigger
Example TRIG:SEQ:SLOP POSITIVE
