Figure 54 Analog trigger output timing advance
Table 12 Analog pulse output
Logic pulse output The signal from the Logic pulse output is a digital representation of the analog
trigger signal and corresponds to the electrical specifications shown in Table 13.
The signal on the Logic pulse output rises to a positive logic signal in advance of
the optical pulse emission. As Figure 55 shows, the rising edge of the logic
trigger occurs shortly after the analog output trigger and remains high for an
order of magnitude longer than its timing advance before the optical pulse. The
signal is typically used for triggering an external application and/or pulse
counting. The signal rate matches the configured repetition rate using CONTROL
or on the front panel.
