22 :MEASure Commands
:MEASure:PWIDth
(see page 1428)
Command Syntax
:MEASure:PWIDth [<source>]
<source> ::= {<digital channels> | CHANnel<n> | FUNCtion<m> | MATH<m>
| WMEMory<r>}
<digital channels> ::= DIGital<d> for the MSO models
<d> ::= 0 to (# digital channels - 1) in NR1 format
<n> ::= 1 to (# of analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
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
