5 Commands by Subsystem

:MEASure:PHASe

(see page 798)

Command Syntax

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

<source1>, <source2> ::= {CHANnel<n> | FUNCtion | MATH}

<n>::={1|2|3|4}forthefour channel oscilloscope models

<n> ::= {1 | 2} for the two channel oscilloscope models

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
