Commands by Subsystem 3

:MEASure:FREQuency

(see page 530)

Command Syntax :MEASure:FREQuency [<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: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)

N O T E This command is not available if the source is FFT (Fast Fourier Transform).

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><NL>

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