FETCh?

Waits for measurements to complete and copies all available measurements to the instrument's output
buffer. The readings remain in reading memory.
Parameter
(none)
Use FETCh? with CONFigure and INITiate. The
ger" 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.

The FETch? query does not erase measurements from the reading memory. You can send the query
l
multiple times to retrieve the same data.
You can store up to 1,000 measurements in the reading memory of the 34460A, 10,000 meas-
l
urements 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 Ques-
tionable Data Register's condition register (see
The instrument clears all measurements from reading memory when the measurement configuration
l
changes, or when any of these commands are executed: INITiate,
*RST, SYSTem:PRESet.

(none)
INITiate
command places the instrument in the "wait-for-trig-
