:MEASure:CPLoss
(see page 1276 )
Command Syntax
:MEASure:CPLoss [<source1>][,<source2>]
<source1> ::= {FUNCtion<m> | MATH<m>}
<source2> ::= {CHANnel<n>}
<m> ::= 1 to (# math functions) in NR1 format
<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
