INITiate[:IMMediate]
Changes the state of the triggering system from "idle" to "wait-for-trigger", and clears the previous set of
measurements from reading memory. Measurements begin when the specified trigger conditions are sat-
isfied following the receipt of INITiate.
Parameter Typical Return
(none) (none)
Return five DC voltage measurements, using a software trigger to start the measurements:
CONF:VOLT:DC 10,0.003
TRIG:SOUR BUS
SAMP:COUN 5

l Storing measurements in reading memory with INITiate is faster than sending measurements to the
instrument's output buffer using READ? (provided you do not send FETCh? until done). The INITiate
command is also an "overlapped" command. This means that after executing INITiate, you can send
other commands that do not affect the measurements.
l You can store up to 1,000 measurements in the reading memory of the 34460A, 10,000 meas-
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 Status System Introduction).
l To retrieve the measurements from the reading memory, use FETCh?. Use DATA:REMove? or R? to
read and erase all or part of the available measurements.
l Use ABORt to return to idle.
