MEASure Group of Commands

initiate the measurement and query the results. See Figure 5-1.

If you need to repeatedly make a given measurement with settings other than the factory defaults, you can use the commands in the SENSe:<measurement> and CALCulate:<measurement> subsystems to set up the measurement. Then use the READ? command to initiate the measurement and query results.

Measurement settings persist if you initiate a different measurement and then return to a previous one. Use READ:<measurement>? if you want to use those persistent settings. If you want to go back to the default settings, use MEASure:<measurement>?.

Configure Commands

 

:CONFigure:<measurement>

 

This command stops the current measurement (if any) and sets up the

 

instrument for the specified measurement using the factory default

 

instrument settings. It sets the instrument to single measurement

 

mode but should not initiate the taking of measurement data unless

 

INIT:CONTinuous is ON. After you change any measurement settings,

 

the READ command can be used to initiate a measurement without

 

changing the settings back to their defaults.

 

In instruments with firmware older then A.05.00 CONFigure initiates

NOTE

 

the taking of data. The data should be ignored. Other SCPI commands

 

can be processed immediately after sending CONFigure. You do not

 

need to wait for the CONF command to complete this ’false’ data

 

acquisition.

 

The CONFigure? query returns the current measurement name.
