:MEASure:ELOSs
Command Syntax
:MEASure:ELOSs [<source>]
<source> ::= {CHANnel<n>| FUNCtion<m> | MATH<m> | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<m> ::= 1 to (# math functions) 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
