Switching the trigger source
Continuous measurement (:INITIATE:CONTINUOUS ON) is the normal trigger state when
using key operation from the front panel. Selecting the internal (INT) trigger source acti-
vates continuous triggering ("free-run"). When external (EXT) triggering is selected, each
external trigger event initiates one measurement. Continuous measurement can be dis-
abled by sending the :INITIATE:CONTINUOUS OFF command via RS-232C or USB.
When continuous measurement is disabled, trigger acceptance is controlled only by the
controller (computer or PLC).
See: For trigger command: See the included application disc.
