source occurs immediately. Subsequent arm events will then occur every
30 seconds. The interval for the timer is set using the :TIMer command.
With MANual selected, the event occurs when the TRIG key is pressed.
With BUS selected, the event occurs when a GET or *TRG command is
sent over the bus.
With NSTest selected, the event occurs when the SOT (start-of-test) low
pulse is received from a component handler via the digital I/O port. This
is used for limit testing.
With PSTest selected, the event occurs when SOT (start-of-test) high
pulse is received from a component handler via the digital I/O port. This
is used for limit testing.
With BSTest selected, the event occurs when SOT (start-of-test) high or
low pulse is received from a component handler via the digital I/O port.
This is used for limit testing.

:TRIGger[:SEQuence[1]][:TCONfigure]:DIRection <name> Control trigger bypass
Parameters <name> = SOURce Enable control source bypass
ACCeptor Disable control source bypass
Query :DIRection? Query state of bypass
