Commands by Subsystem 3

:MEASure:DUTYcycle

(see page 530)

Command Syntax :MEASure:DUTYcycle [<source>]

<source> ::= {CHANnel<n> FUNCtion MATH}

<n> ::= {1 2 3 4} for the four channel oscilloscope models <n> ::= {1 2} for the two channel oscilloscope models

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.

N O T E

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

the source is FFT (Fast Fourier Transform).

 

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
