4263B
Initiate State
If the trigger system is on a downward path, it travels directly through the Initiate state
without restrictions . If the trigger system is on an upward path, and :INITiate:CONTinuous is
ON , then it exits downward to an Trigger Event Detection state . If the trigger system is on an
upward path and :INITiate:CONTinuous is OFF , then it exits upward to the idle state .
Trigger Event Detection State
If the trigger system is on a downward path, it branches as follows .
Figure 5-7. Inside an Trigger Event Detection State
SOURce The :TRIGer:SOURce command species which particular input can
generate the event required to continue the downward path.
DELay The TRIGger:DELay command allows you to specify a time delay after
trigger signal is detected. F or example , you may want to delay acquiring
data until 5 ms after the positive edge to allow the measured signal to settle .
Sending *RST sets:TRUGger:DELay to zero .
IMMediate The :TRIGger:IMMediate command bypasses event detection, DELay
qualications one time . The upward path through the Trigger Event
Detection state contains only one condition. If the condition is satised, the
trigger system exits upward.
Sequence Operation State
The downward entrance to the Sequence Operation state forces the 4263B to start a
measurement. An upward exit is not allowed until the measurement is complete .
