:TRIGger:SLOPe:WHEN
Syntax
:TRIGger:SLOPe:WHEN <when>
:TRIGger:SLOPe:WHEN?
Description Set or query the trigger condition in slope trigger.
Parameter
Name
<when>
Explanation PGReater/PLESs: you need to specify a time value (refer to :TRIGger:SLOPe:TIME).

The oscilloscope triggers when the positive slope time of the input signal is
greater/lower than the specified time.
NGReater/NLESs: you need to specify a time value (refer to :TRIGger:SLOPe:TIME).

The oscilloscope triggers when the negative slope time of the input signal is
greater/lower than the specified time.
PGLess/NGLess: you need to specify an upper limit (refer

to :TRIGger:SLOPe:TUPPer) and a lower limit (refer to :TRIGger:SLOPe:TLOWer) of
the time. The oscilloscope triggers when the positive/negative slope time of the input
signal is greater than the specified lower limit and lower than the specified upper
limit.
Return The query returns PGR, PLES, NGR, NLES, PGL or NGL.
