(see page 658)
Command Syntax
:MEASure:NWIDth [<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:NWIDth command installs a screen measurement and starts
a negative pulse width measurement. If the optional source parameter is
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
