:ARM[:SEQuence[1]][LAYer[1]]:SOURce <name>Specify arm event control
source
:TRIGger[:SEQuence[1]]:SOURce <name>Specify trigger event control source
<name> = IMMediate
TLINk
TIMer
MANual
BUS
NSTest
PSTest
BSTest
Only IMMediate and TLINk are available as trigger layer control sources.
:SOURce?
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 using the trigger link.
The following control sources are not available for the trigger layer. For more information
on these control sources, see
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 programmed 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 SOT (start-of-test) low pulse is
received. This is used for limit testing.
With PSTest selected, the event occurs when SOT (start-of-test) high pulse is
received. This is used for limit testing.
With BSTest selected, the event occurs when SOT (start-of-test) high or low pulse
is received. This is used for limit testing.
:ARM[:SEQuence[1]][:LAYer[1]]:TIMer <n>Set interval for arm layer timer
<n> = 0.001 to 9999.999Specify timer interval in seconds
10000.00 to 99999.99Specify timer interval in seconds
:TIMer?
These commands are used to set the interval for the timer. Note that the timer is in
effect only if the timer is the selected control source.
