:MEASure:FREQuency

(see page 798)

Command Syntax

:MEASure:FREQuency [<source>]

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

<digital channels> ::= DIGital0,..,DIGital15 for the MSO models

<n>::={1|2|3|4}forthefour channel oscilloscope models

<n> ::= {1 | 2} for the two channel oscilloscope models

The :MEASure:FREQuency command installs a screen measurement and

starts a frequency measurement. If the optional source parameter is

specified, the current source is modified.

IF the edge on the screen closest to the trigger reference is rising:

THEN frequency = 1/(time at trailing rising edge - time at leading rising

edge)

ELSE frequency = 1/(time at trailing falling edge - time at leading falling

edge)

Query Syntax

:MEASure:FREQuency? [<source>]

The :MEASure:FREQuency? query measures and outputs the frequency of

the cycle on the screen closest to the trigger reference.

Return Format

<source> ::= frequency in Hertz in NR3 format
