Measure Commands

:MEASure:PWIDth

Command
:MEASure:PWIDth [<source>]
The :MEASure:PWIDth command measures the width of the first positive
pulse on the screen using the mid- threshold levels of the waveform (50%
levels with standard measurements selected). Sources are specified with
the :MEASure:SOURce command or with the optional parameter following
the :MEASure:PWIDth command.
The algorithm is:
If the first edge on the screen is rising,
then
else
<source> {CHANnel<N> | FUNCtion<F> | DIGital<M> | WMEMory<N> | CLOCk |
MTRend | MSPectrum | EQUalized}
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source.
<N>
CHANnel<N> is an integer, 1- 4.
WMEMory<N> is an integer, 1- 4.
<F> FUNCtion<F> is an integer, 1- 16.
<M> An integer, 0- 15. Digital channels are available on mixed- signal
oscilloscopes.
Example This example measures the width of the first positive pulse on the screen.
myScope.WriteString ":MEASure:PWIDth CHANnel1"
Query
:MEASure:PWIDth?[<source>]
The :MEASure:PWIDth? query returns the measured width of the first
positive pulse of the specified source.
Returned Format
[:MEASure:PWIDth] <value>[,<result_state>]<NL>

pwidth = time at the first falling edge - time at the
first rising edge
pwidth = time at the second falling edge - time at the
first rising edge
