MEASure{:ARRay | [:SCALar]} :POWer:WAVelength?
Returns wavelength values.
:POWer:WAVelength? [<expected_value>[,<resolution>]]
Used With <expected_value>
SCALar optional
ARRay
ignored
a. Although ignored, this argument must be present if the resolution argument is specified.
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 wavelength that is closest to the <expected_value> parameter. Default units for
<expected_value> parameter are in meters.
When used with an :ARRay command, an array of wavelengths is returned. The dis-
play is placed in the list-by-wavelength mode.
The <resolution> parameter sets the resolution of the measurement. It is a unitless
number whose value will be limited to either 0.01 or 0.001 (whichever is closer).
Returned values are in meters. Displayed units are nanometers. Power 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 The highest wavelength signal
MINimum The lowest wavelength signal
DEFault The current marker position
MAXimum 0.01 resolution (fast update)
MINimum 0.001 resolution (normal)
