(see page 860)
Command Syntax
:MEASure:NWIDth [<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: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><NL>
<value> ::= negative pulse width in seconds in NR3 format
