:TRIGger:SLOPe:WHEN
Syntax
:TRIGger:SLOPe:WHEN <when>
:TRIGger:SLOPe:WHEN?
Description
Set or query the trigger condition in slope trigger.

Discrete
{PGReater|PLESs|NGReater|
NLESs|PGLess|NGLess}
PGReater
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
Format
The query returns PGR, PLES, NGR, NLES, PGL, or NGL.
Example
:TRIGger:SLOPe:WHEN NLESs /*Set the trigger condition to NLESs*/
:TRIGger:SLOPe:WHEN? /*The query returns NLES*/
:TRIGger:SLOPe:TIME
Syntax
:TRIGger:SLOPe:TIME <time>
:TRIGger:SLOPe:TIME?
Description
Set or query the time value in slope trigger. The default unit is s.
Parameter
Name
Type
Range
Default
<time>
Real
8ns to 10s
PGReater, NGReater: 1μs
PLESs, NLESs: 2μs
Explanation
This command is available when the trigger condition (refer to :TRIGger:SLOPe:WHEN) is
PGReater, PLESs, NGReater, and NLESs.
Return
Format
The query returns the time value in scientific notation.
Example
:TRIGger:SLOPe:TIME 0.000003 /*Set the time value to 3μs*/
:TRIGger:SLOPe:TIME? /*The query returns 3.000000e-06*/
