:MEASure Power Commands
:MEASure:ELOSs
(see page 1208 )
Command Syntax
:MEASure:ELOSs [<source>]
<source> ::= {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:ELOSs command installs an energy 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.
Energy loss =

(Vds
n
* Id
n
) * sample size, where n is each sample.
Query Syntax
:MEASure:ELOSs? [<source>]
The :MEASure:ELOSs query returns the switching loss in joules.
Return Format
<return_value><NL>
<return_value> ::= the energy loss value in NR3 format
