RIGOL Chapter 2 Command System
2-224 DS4000E Programming Guide
Remarks
When the trigger condition is "PGLess" or "NGLess" (refer to the :TRIGger:SLOPe:WHEN command), the
time lower limit must be smaller than the current time upper limit (refer to the :TRIGger:SLOPe:TUPPer
command).
Return Format
The query returns the time lower limit in scientific notation.
:TRIGger:SLOPe:TUPPer
Syntax
:TRIGger:SLOPe:TUPPer <time>
:TRIGger:SLOPe:TUPPer?
Description
Sets or queries the time upper limit of Slope trigger when the trigger condition is "PLESs", "NLESs",
"PGLess", or "NGLess" (refer to the :TRIGger:SLOPe:WHEN command). The default unit is s.
Parameter
Name Type Range Default
<time> Real
When the trigger condition is "PLESs" or "NLESs": 10 ns
to 1 s
When the trigger condition is "PGLess" or "NGLess": 20
ns to 1 s
2 us
Remarks
When the trigger condition is "PGLess" or "NGLess" (refer to the :TRIGger:SLOPe:WHEN command), the
time upper limit must be greater than the current time lower limit (refer to the :TRIGger:SLOPe:TLOWer
command).
Return Format
The query returns the timer upper limit in scientific notation.
:TRIGger:SLOPe:WHEN
Syntax
:TRIGger:SLOPe:WHEN <cond>
:TRIGger:SLOPe:WHEN?
Description
Sets or queries the trigger condition of Slope trigger.
Parameter
Name Type Range Default
<cond> Discrete {PGReater|PLESs|NGReater|NLESs|PGLess|NGLess} PGReater
Remarks

PGReater: indicates that the oscilloscope triggers when the positive slope time of the input signal is
greater than the specified time (refer to the :TRIGger:SLOPe:TLOWer command).

PLESs: indicates that the oscilloscope triggers when the positive slope time of the input signal is
smaller than the specified time (refer to the :TRIGger:SLOPe:TUPPer command).

NGReater: indicates that the oscilloscope triggers when the negative slope time of the input signal is
greater than the specified time (refer to the :TRIGger:SLOPe:TLOWer command).

NLESs: indicates that the oscilloscope triggers when the negative slope time of the input signal is
smaller than the specified time (refer to the :TRIGger:SLOPe:TUPPer command).
