INITiate
/* Send the trigger event */
TRIGger:IMMediate
/* Channels 1 and 2 output the programmed voltages */
Note that the channels must be set for triggered output (using the SOURce
subsystem) before the trigger system is changed to the wait-for-trigger state
(using the
INITiate command). If you send the SOURce n commands after
the INITiate command, the following error is reported:
+3014 Illegal while initiated
Once the outputs have been triggered (using TRIGger:IMMediate in the
previous example) the trigger system is set back to the trigger idle state. New
triggered channel output values can be programmed and the trigger system put
in the wait-for-trigger state. The triggering process is illustrated below.
Note Once an output is enabled and a voltage or current output, that value
remains on the output. Sending subsequent
SOUR n :VOLT:TRIG or
SOUR n :CURR:TRIG commands will not change the output value until the
trigger event is received. The output may be disabled (output relay opened)
with the
OUTP n OFF command.
The trigger source set using the TRIGger:SOURce command remains in
effect until it is changed or a reset occurs. Following a reset ( *RST ) the
trigger source is set to HOLD .
