20 :MEASure Commands

:MEASure:PWIDth

(see page 790)

Command Syntax

:MEASure:PWIDth [<source>]

<source> ::= {<digital channels> | CHANnel<n> | FUNCtion | MATH

| WMEMory<r>}

<digital channels> ::= DIGital<d> for the MSO models

<n> ::= 1 to (# of analog channels) in NR1 format

<r> ::= 1-2 in NR1 format

<d> ::= 0 to (# digital channels - 1) 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> ::= width of positive pulse in seconds in NR3 format
