22 :MEASure Commands

:MEASure:DUTYcycle

(see page 1276)

Command Syntax

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

positive 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 positive 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).
