BTS Master Programming Manual : TDSCDMA Commands : :FETCh Subsystem
 
:FETCh Subsystem
This set of commands returns the most recent measurement data of the active measurement. They will not switch to another measurement.
To make a new measurement, use the INITiate command. To get new measurement data, use the READ or MEASure query commands.
