24 :MEASure Commands

:MEASure:PHASe

(see page 1610)

Command Syntax

:MEASure:PHASe [<source1>][,<source2>]

<source1>, <source2> ::= {CHANnel<n> | FUNCtion<m> | MATH<m> | WMEMory<r

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

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

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

The :MEASure:PHASe command places the instrument in the continuous

measurement mode and starts a phase measurement.

Query Syntax

:MEASure:PHASe? [<source1>][,<source2>]

The :MEASure:PHASe? query measures and returns the phase between the

specified sources.

A phase measurement is a combination of the period and delay measurements.

First, the period is measured on source1. Then the delay is measured between

source1 and source2. The edges used for delay are the source1 rising edge used

for the period measurement closest to the horizontal reference and the rising edge

on source 2. See :MEASure:DELay for more detail on selecting the 2nd edge.

The phase is calculated as follows:

phase = (delay / period of input 1) x 360

Return Format

<value> ::= the phase angle value in degrees in NR3 format
