Agilent InfiniiVision 2000 X-Series Oscilloscopes Programmer's Guide 355

:MEASure:PERiod

(see page 790)

Command Syntax

:MEASure:PERiod [<source>]

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

| WMEMory<r>}

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

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

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

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