MEASure{:ARRay | [:SCALar]} :POWer?
Returns amplitude values.
:POWer? [<expected_value>[,<resolution>]]
Used With <expected_value>
SCALar optional
ARRay ignored
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 dis-
play is placed in the list-by-power mode.
Returned values are in the current power units. Wavelength 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.
MAXimum Displays the highest power signal
MINimum Displays the lowest power signal
DEFault Displays the signal at the current marker position
