21 :MEASure Power Commands
:MEASure:ANGLe
(see page 1138)
Command Syntax
:MEASure:ANGLe [<source1>][,<source2>]
<source1>, <source2> ::= {CHANnel<n>}
<n> ::= 1 to (# analog channels) in NR1 format
The :MEASure:ANGLe command installs a power phase angle measurement
on screen.
The <source1> parameter is the channel probing voltage and the <source2>
parameter is the channel probing current. These sources can also be
specified by the :MEASure:SOURce command.
Phase angle is a measure of power quality. In the power triangle (the
right triangle where apparent_power
2
= real_power
2
+ reactive_power
2
),
phase angle is the angle between the apparent power and the real power,
indicating the amount of reactive power. Small phase angles equate to less
reactive power.
Query Syntax
:MEASure:ANGLe? [<source1>][,<source2>]
The :MEASure:ANGLe query returns the measured power phase angle in
degrees.
Return Format
<return_value><NL>
<return_value> ::= the power phase angle in degrees in NR3 format
