Trigger = AUTO automatically selects the trigger source best suited for the present

and *TRG.
Trigger = TIMER uses a signal internally generated every interval set by the Period
parameter.
Trigger = INT1 or INT2 uses a signal from the internal bus 1 or 2, respectively.
Trigger = LAN uses the LXI trigger.
Trigger = EXTn uses a signal from the DIO pin n which is an output port of the
Digital I/O D-sub connector on the rear panel. n=1 to 7.
