:MEASure:PWIDth
(see page 530)
Command Syntax :MEASure:PWIDth [<source>]
<source> ::= {CHANnel<n> | FUNCtion | MATH}
<n>::={1|2|3|4}forthefour channel oscilloscope models
<n> ::= {1 | 2} for the two channel oscilloscope models
The :MEASure:PWIDth command installs a screen measurement and starts
the positive pulse width measurement. If the optional source parameter is
specified, the current source is modified.
Query Syntax :MEASure:PWIDth? [<source>]
The :MEASure:PWIDth? query measures and outputs the width of the
displayed positive pulse closest to the trigger reference. Pulse width is
measured at the midpoint of the upper and lower thresholds.
IF the edge on the screen closest to the trigger is falling:
THEN width = (time at trailing falling edge - time at leading rising edge)
ELSE width = (time at leading falling edge - time at leading rising edge)
Return Format <value><NL>
<value> ::= width of positive pulse in seconds in NR3 format
