Description These commands are used to select the event control source. With
IMMediate, selected operation immediately continues.
A specific event can be used to control operation. With TLINk selected,
operation continues when a trigger pulse is received via the Trigger
Link.
NOTE The following control sources are not available for the trigger layer.
With TIMer selected, the event occurs at the beginning of the timer
interval, and every time it times out. For example, if the timer is pro-
grammed for a 30 second interval, the first pass through the control
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 start-of-test (SOT)
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 start-of-test (SOT) high
pulse is received from a component handler via the Digital I/O port.
This is used for limit testing.
