Agilent InfiniiVision 5000 Series Oscilloscopes Programmer's Guide 281

:MEASure:DUTYcycle

(see page 658)

Command Syntax

:MEASure:DUTYcycle [<source>]

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

<n>::={1|2|3|4}forthefour 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.

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

Example Code • "Example Code" on page 297

NOTE

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

the source is FFT (Fast Fourier Transform).
