22 :MEASure Commands

:MEASure:NWIDth

(see page 1276)

Command Syntax

:MEASure:NWIDth [<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:NWIDth command installs a screen measurement and starts a

negative pulse width measurement. If the optional source parameter is not

specified, the current source is modified.

Query Syntax

:MEASure:NWIDth? [<source>]

The :MEASure:NWIDth? query measures and outputs the width of the negative

pulse on the screen closest to the trigger reference using the midpoint between

the upper and lower thresholds.

FOR the negative pulse closest to the trigger point:

width = (time at trailing rising edge - time at leading falling edge)

Return Format

<value> ::= negative pulse width in seconds in NR3 format
