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 com-
mand 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.
