INITiate[:IMMediate]
Syntax
INITiate[:IMMediate]
Description
This command changes the state of the triggering system from the "idle" state to the "wait-for-trigger"
state. Measurements will begin when the specified trigger conditions are satisfied following the receipt of
the INITiate command. Note that the INITiate command also clears the previous set of measurements
from memory.
Remarks
l Storing measurements in memory using the INITiate command is faster than sending measurements to
the output buffer using the READ? command. The INITiate command is also an "overlapped" com-
mand. This means that after executing the INITiate command, you can send other commands that do
not affect the measurements.
l You can store up to 1,000,000 measurements in the reading memory. If memory overflows, the new
measurements will overwrite the first (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.
l To retrieve the measurements from memory, use the FETCh? command. Use DATA:REMove? to remove
data points. Or use the R? command to read and remove all of the available data.
l The ABORt command may be used to return to idle.
Example
The following program segment shows how to use the INITiate command with the CONFigure and FETCh?
commands. The INITiate command places the instrument in the "wait-for-trigger" state, triggers a meas-
urement when the rear-panel Trig In BNC is pulsed (low by default), and then sends the measurements to
memory. The FETCh? command transfers the measurements from memory to the instrument's output buf-
fer.
