21 :MEASure Power Commands
:MEASure:PLOSs
(see page 1138)
Command Syntax
:MEASure:PLOSs [<source>]
<source> ::= {CHANnel<n>| FUNCtion | MATH | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<r> ::= 1-2 in NR1 format
The :MEASure:PLOSs command installs a power loss 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.
Power loss is P
n
= Vds
n
* Id
n
, where n is each sample.
Query Syntax
:MEASure:PLOSs? [<source>]
The :MEASure:PLOSs query returns the switching loss in watts.
Return Format
<return_value><NL>
<return_value> ::= the power loss value in NR3 format
