FETCh?

Waits for measurements to complete and copies all available measurements to the instrument's output buffer. The readings remain in reading memory.

Parameter	Typical Return
(none)	(none)
Use FETCh? with CONFigure and INITiate. The INITiate command places the instrument in the "wait-for-trigger" state, triggers a measurement when the rear-panel Ext Trig input is pulsed (low by default), and sends the measurement to reading memory. The FETCh? query transfers the measurement from reading memory to the instrument's output buffer. CONF:VOLT:DC 10,0.003 TRIG:SOUR EXT SAMP:COUN 4 INIT FETC?

The FETch? query does not erase measurements from the reading memory. You can send the query multiple times to retrieve the same data.
You can store up to 1,000 measurements in the reading memory of the 34460A, 10,000 measurements on the 34461A, 50,000 measurements on the 34465A/70A (without the MEM option), or 2,000,000 measurements on the 34465A/70A (with the MEM option). If reading memory overflows, new measurements overwrite the oldest measurements stored; the most recent measurements are always preserved. No error is generated, but the Reading Mem Ovfl bit (bit 14) is set in the Questionable Data Register's condition register (see Status System Introduction).
The instrument clears all measurements from reading memory when the measurement configuration changes, or when any of these commands are executed: INITiate, MEASure:<function>?, READ?, *RST, SYSTem:PRESet.
