:MEASure:DUTYcycle

(see page 792)

Command Syntax

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

duty cycle measurement on the current :MEASure:SOURce. If the optional source

parameter is specified, the current source is modified.

Query Syntax

:MEASure:DUTYcycle? [<source>]

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

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

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