Measurement instructions give quick results
The easiest way to measure wavelength, frequency, or power is to use
the MEASure command. The MEASure command is one of four mea-
surement instructions: MEASure, READ, FETCh, and CONFigure. The
syntax for measurement instructions is documented in
Instructions" on page 4-
Each measurement instruction has an argument that controls the mea-
surement update rate. This is equivalent to using the NORMAL and
FAST softkeys.
:MEASure command
MEASure configures the Agilent 86120C, captures new data, and que-
ries the data all in one step. For example, to measure the longest
wavelength, send the following command:
:MEASure:SCALar:POWer:WAVelength? MAX

Specifying SCALar places the display in the single wavelength format
and returns a single value to the computer. Specifying ARRay places
the display in the List by Power or List by WL modes; an array of data is
returned to the computer.
