21 :MEASure Power Commands
:MEASure:CPLoss
(see page 1138)
Command Syntax
:MEASure:CPLoss [<source1>][,<source2>]
<source1> ::= {FUNCtion | MATH}
<source2> ::= {CHANnel<n>}
<n> ::= 1 to (# analog channels) in NR1 format
The :MEASure:CPLoss command installs a power loss per cycle
measurement on screen.
The <source1> 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 per cycle is Pn = (Vdsn * Idn ) * ( Time range of zoom
window) * ( Counter measurement of the voltage of the switching signal),
where n is each sample.
This measurement operates when in zoom mode and the counter
measurement is installed on the voltage of the switching signal.
Query Syntax
:MEASure:CPLoss? [<source1>][,<source2>]
The :MEASure:CPLoss query returns the switching loss per cycle in watts.
Return Format
<return_value><NL>
<return_value> ::= the switching loss per cycle value in NR3 format
