MEASure{:ARRay | [:SCALar]} :POWer:WAVelength?
[<expected_value>[,<resolution>]]
Returns wavelength values.
Description
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> param-
eter are in meters.
When used with an :ARRay command, an array of wave-
lengths is returned. The display 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.

a. Although ignored, this argument must be present if the resolution
argument is specified.
optional
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
