:TRIGger:PULSe:WHEN
Syntax :TRIGger:PULSe:WHEN <when>
:TRIGger:PULSe:WHEN?
Description Set or query the trigger condition in pulse width trigger.
Parameter
Name
<when>
Explanation PGReater/PLESs: you need to specify a pulse width (refer

to :TRIGger:PULSe:WIDTh). The oscilloscope triggers when the positive pulse width
of the input signal is greater/lower than the specified Pulse Width.
NGReater/NLESs: you need to specify a pulse width (refer

to :TRIGger:PULSe:WIDTh). The oscilloscope triggers when the negative pulse width
of the input signal is greater/lower than the specified Pulse Width.
PGLess/NGLess: you need to specify an upper (refer to :TRIGger:PULSe:UWIDth)

and a lower (refer to :TRIGger:PULSe:LWIDth) pulse width. The oscilloscope triggers
when the positive/negative pulse width of the input signal is greater than the
specified lower pulse width and lower than the upper pulse width.
Return The query returns PGR, PLES, NGR, NLES, PGL, or NGL.

:TRIGger:PULSe:WIDTh
Syntax :TRIGger:PULSe:WIDTh <width>
:TRIGger:PULSe:WIDTh?
Description Set or query the pulse width in pulse width trigger. The default unit is s.
Parameter
Name
<width>
Explanation This command is available when the trigger condition (refer to :TRIGger:PULSe:WHEN) is
