24 :MEASure Commands

:MEASure:NDUTy

(see page 1610)

Command Syntax

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

negative duty cycle measurement on the current :MEASure:SOURce. If the

optional source parameter is specified, the current source is modified.

Query Syntax

:MEASure:NDUTy? [<source>]

The :MEASure:NDUTy? query measures and outputs the negative duty cycle of the

signal specified by the :MEASure:SOURce command. The value returned for the

duty cycle is the ratio of the negative pulse width to the period. The negative pulse

width and the period of the specified signal are measured, then the duty cycle is

calculated with the following formula:

-duty cycle = (-pulse width/period)*100

Return Format

<value> ::= ratio of negative pulse width to period in NR3 format

NOTE

The signal must be displayed to make the measurement. This command is not available if the

source is FFT (Fast Fourier Transform).
