:MEASure:CRESt
(see page 1138)
Command Syntax
:MEASure:CRESt [<source>]
<source> ::= {CHANnel<n>| FUNCtion | MATH}
<n> ::= 1 to (# analog channels) in NR1 format
The :MEASure:CRESt command installs a crest factor measurement on
screen.
The <source> parameter is the channel probing current or voltage. This
source can also be specified by the :MEASure:SOURce command.
Crest factor is a measure of power quality. It is the ratio between the
instantaneous peak AC line current (or voltage) required by the load and
the RMS current (or voltage). For example: Ipeak / IRMS or Vpeak /
VRMS.
Query Syntax
:MEASure:CRESt? [<source>]
The :MEASure:CRESt query returns the measured crest factor.
Return Format
<return_value><NL>
<return_value> ::= the crest factor value in NR3 format
