20 :MEASure Commands
:MEASure:DUTYcycle
(see page 782)
Command Syntax
:MEASure:DUTYcycle [<source>]
<source> ::= {CHANnel<n> | FUNCtion | MATH | WMEMory<r> | EXTernal}
<n> ::= 1 to (# of analog channels) in NR1 format
<r> ::= 1-2 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><NL>
<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).
