Single Sequence
A sequence is the repetition of one pulse set “X” number of times. Figure 46 shows a
sequence with the pulse set repeated three (3) times.
Figure 46. Sequence with 3 Repetitions
The EXPOSE signal remains high for the duration of the sequence and goes low
approximately 15 ns after sequence completion.
Supported Timing Generator Trigger Modes:
Trigger per Pulse: Each pulse of the single sequence is initiated by its own trigger (all
triggers must be from the same source and all must be either internal or external). See
Figure 47.
Supported Trigger Sources:
Source 1: Timing Generator internal trigger. Each pulse set of the sequence
is initiated by the timing generator’s internal trigger.
Source 2: External Trigger (on TRIGGER IN BNC). Each pulse set is
initiated by an external trigger.
