PGReater
Remarks
 PGReater: indicates that the oscilloscope triggers when the positive pulse width of the input signal is
greater than the specified pulse width (refer to the :TRIGger:PULSe:LWIDth command).
 PLESs: indicates that the oscilloscope triggers when the positive pulse width of the input signal is
smaller than the specified pulse width (refer to the :TRIGger:PULSe:UWIDth command).
 NGReater: indicates that the oscilloscope triggers when the negative pulse width of the input signal is
greater than the specified pulse width (refer to the :TRIGger:PULSe:LWIDth command).
 NLESs: indicates that the oscilloscope triggers when the negative pulse width of the input signal is
smaller than the specified pulse width (refer to the :TRIGger:PULSe:UWIDth command).
 PGLess: indicates that the oscilloscope triggers when the positive pulse width of the input signal is
greater than the lower limit of the specified pulse width (refer to the :TRIGger:PULSe:LWIDth
command) and smaller than the upper limit of the specified pulse width (refer to
the :TRIGger:PULSe:UWIDth command).
 NGLess: indicates that the oscilloscope triggers when the negative pulse width of the input signal is
greater than the lower limit of the specified pulse width (refer to the :TRIGger:PULSe:LWIDth
command) and smaller than the upper limit of the specified pulse width (refer to
the :TRIGger:PULSe:UWIDth command).
Return Format
The query returns PGR, PLES, NGR, NLES, PGL, or NGL.
