MEASure Commands

These command take the instrument from its current state, enable the specified measurement and put the instrument into single sweep mode. They correct any parameters that are invalid given the new measurement state such that a valid measurement can take place. Other settings may be changed; see the documentation of CONFigure for each measurement. They then initiate the measurement. When the measurement is complete, they return the result.

To make a measurement with settings other than the “default” measurement settings applied by CONFigure, do the following:

•	Send the appropriate CONFigure command to set the desired measurement.

•	Modify the settings as required.

•	Send the appropriate READ command to measure and return the result.

To get the current measurement data, use the appropriate FETCh command.
