User`s manual
• If a stop trigger is received while the start trigger sequence is in the idle or
wait-for-arm states, it is ignored with no error generated.
• If the start trigger sequence is on the last of ARM[:STARt]:LAYer2:COUNt arm
cycles, a stop trigger places the trigger system in the idle state at the end of the
current waveform repetition.
• A stop trigger differs from the ABORt command in that ABORt terminates all start
arm cycles immediately, whereas a stop trigger terminates only the current arm
cycle, at the end of the current waveform repetition.
• Use the TRIGger:STOP:SLOPe command to select the active edge (rising or
falling) for the front panel “Stop Trig/FSK/Gate In” BNC when used as the stop
trigger source.
• The front panel “ Stop Trig/FSK/Gate In” BNC is a three-use connector; for FSK
control, as a stop trigger source, or as a sample gate source. Only one of these
uses may be active at any time.
• If a VXIbus TTLTrg trigger line is used as the stop trigger source, then no
TTLTrg trigger lines can be used for FSK control or as the gating source.

*RST Condition: TRIGger:STOP:SOURce HOLD
Example Setting the Stop Trigger Source
TRIG:STOP:SOUR TTLT1 Selects VXIbus trigger line TTLTRG1* as
source.
:SWEep[:IMMediate]
TRIGger:SWEep[:IMMediate] advances a frequency sweep or list to the next
frequency regardless of the selected trigger source. The trigger system must have
been initiated and the sweep trigger sequence must be in the wait-for-trigger state.
The selected trigger source remains unchanged.
Comments • Executing this command when frequency sweeps or lists are not enabled, or with the
sweep trigger sequence not in the wait-for-trigger state generates Error -211,"Trigger
ignored".
• Executable when Initiated: Yes
• Coupling Group: none
