Keithley 6430 User Manual

SCPI Command Reference 17-105
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.
:TIMer <n>
:ARM[:SEQuence[1]][:LAYer[1]]:TIMer <n> Set interval for arm layer timer
Parameters <n> = 0.001 to 9999.999 Specify timer interval in seconds
10000.00 to 99999.99 Specify timer interval in seconds
Query :TIMer? Query programmed timer interval
Description 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.
:DIRection <name>
:ARM[:SEQuence[1]][LAYer[1]][:TCONfigure]:DIRection <name>Control arm bypass
: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
Description This command is used to enable (SOURce) or disable (ACCeptor) control
source bypass. When enabled, operation will loop around the control source
on the first pass in the layer. After that, repeat passes in the layer are held up
and will wait for the programmed control source event.
INPut <event list>
:TRIGger[:SEQuence[1]][:TCONfigure][:ASYNchronous]:INPut <event list> Enable event detectors
Parameters <event list> = SOURce Enable Source Event Detector
DELay Enable Delay Event Detector
SENSe Enable Measure Event Detector
NONE Disable all event detectors in Trigger Layer
NOTE Each event in the list must be separated by a comma (i.e. trigger:input source, delay,
sense).
Query :INPut? Query enabled event detectors in Trigger Layer
