Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 595

:MEASure:FREQuency

(see page 1610)

Command Syntax

:MEASure:FREQuency [<source>]

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

| WMEMory<r>}

<digital channels> ::= DIGital<d> for the MSO models

<d> ::= 0 to (# digital channels - 1) in NR1 format

<n> ::= 1 to (# of analog channels) in NR1 format

<m> ::= 1 to (# math functions) in NR1 format

<r> ::= 1 to (# ref waveforms) in NR1 format

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
