MEASure{:ARRay | [:SCALar]}:POWer? [<expected_value>[,<resolution>]]
Description
<expected_value>
Constants
Examples
Returns amplitude values.
Used With
SCALar
ARRay
When used with a :SCALar command, a single value is
returned. The display is placed in the single-wavelength
mode, and the marker is placed on the signal having a
power level that is closest to the <expected_value>
parameter.
When used with an :ARRay command, an array of
amplitudes is returned. The display is placed in the list-
by-power mode.
Returned values are in the current power units. Wave-
length units are not affected.
CONFigure command
When this function is used with the CONFigure command, the
query question mark character "?" must not be included in the
string. However, the FETCh, READ, and MEASure command are
queries and require the question mark. Refer to the examples
for this command.
