:MEASure Commands

:MEASure:PHASe

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> ::= 1-4 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:
Return Format
<value><NL>
<value> ::= the phase angle value in degrees in NR3 format
