Making Measurements

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 “Measurement Instructions” on page 4- 15.

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
