Measurement Instructions

Use the measurement instructions documented in this section to per- form measurements and return the desired results to the computer. Four basic measurement instructions are used: CONFigure, FETCh, READ, and MEASure. Because the command trees for each of these four basic measurement instructions are identical, only the MEASure tree is documented.

To perform a measurement, append to the measurement instruction a POWer or LENGth function. The POWer functions select power, fre- quency, wavelength, or wave number measurements.

When the :SCALar command is used, data for a single measurement value is returned. When the :ARRay command is used, multiple data values are returned.

The MEASure measurement instruction always acquires new measure- ment data. In order to obtain both wavelength and power values from the same measurement data, use two FETCh commands. This is shown in the following program fragment:

OUTPUT 720;”:INIT:CONT OFF;”

OUTPUT 720;”:CONF:ARR:POW MAX”

OUTPUT 720;”:INIT:IMM”

OUTPUT 720;”:FETC:ARR:POW?”

ENTER 720:powers$

OUTPUT 720;”:FETC:ARR:POW:WAV?”

ENTER 720:wavelengths$

In the example above, the data in the power and wavelength arrays are returned in the same order so that powers can be matched to wavelengths. You can also send a MEASure command followed by a FETCh command.
