Details
This command is used to select the event that starts the selected test sequence. When the selected
control source event occurs, the test starts.
With MANual selected, the test starts when the SEQ key is pressed.
With IMMediate selected, the test starts as soon as the instrument is taken out of the idle state. The
:INITiate and :INITiate:CONTinuous ON commands take the instrument out of the idle state.
Note that if the instrument is already in the continuous measurement mode (not in idle), the test starts
as soon as IMMediate is selected.
With BUS selected, the test starts when a bus trigger (*TRG or GET) is sent over the bus.
With TLINk selected, the test starts when an external trigger is received through the TRIG LINK
connector on the rear panel. The :TLINe command is used to select which trigger link line to use for
the input trigger.
With LCLOsure selected, the test starts when the test fixture lid is closed. This only works for test
fixtures (such as the Model 8009) that incorporate the safety interlock feature. If any sequence is
armed when this command is sent, it does not take effect until the next sequence arm event.
:TSOurce? queries the control source to start test.
