:MEASure Commands 20

Keysight InfiniiVision DSOX1204A/G Oscilloscopes Programmer's Guide 371

:MEASure:PERiod

(see page 798)

Command Syntax

:MEASure:PERiod [<source>]

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

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

<r> ::= 1-2 in NR1 format

The :MEASure:PERiod command installs a screen measurement and starts the

period measurement. If the optional source parameter is specified, the current

source is modified.

Query Syntax

:MEASure:PERiod? [<source>]

The :MEASure:PERiod? query measures and outputs the period of the cycle closest

to the trigger reference on the screen. The period is measured at the midpoint of

the upper and lower thresholds.

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

THEN period = (time at trailing rising edge - time at leading rising edge)

ELSE period = (time at trailing falling edge - time at leading falling edge)

Return Format

<value> ::= waveform period in seconds in NR3 format
