Boonton 9240 Series RF Voltmeter
5.5.5 FETCh Queries
The FETCh? group of queries is used to return specific measurement data from a measurement cycle that has been INITiated
and is complete or free-running. FETCh? performs the data output portion of the measurement. FETCh? does not start a
new measurement, so a series of FETCh? queries may be used to return more than one set of processed measurements from a
complete set of acquired data. FETCh? usually returns the current value of measurements, and should be used anytime free
running data acquisition is taking place (INITiate:CONTinuous ON). If FETCh? is used for single measurements
(INITiate:CONTinuous OFF), no data will be returned until a measurement has been INITiated and is complete.
