23 :MEASure Power Commands
:MEASure:REAL
(see page 1428)
Command Syntax
:MEASure:REAL [<source>]
<source> ::= {CHANnel<n>| FUNCtion<m> | MATH<m>}
<n> ::= 1 to (# analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
The :MEASure:REAL command installs a real power measurement on screen.
The <source> parameter is typically a math multiply waveform or other waveform
that represents power (voltage * current). This source can also be specified by the
:MEASure:SOURce command.
Real power is a measure of power quality. It is the portion of power flow that,
averaged over a complete cycle of the AC waveform, results in net transfer of
energy in one direction.
Query Syntax
:MEASure:REAL? [<source>]
The :MEASure:REAL query returns the measured real power.
Return Format
<return_value><NL>
<return_value> ::= the real power value in NR3 format
