Synchronization output ports
Note: If the port is not in use, ensure to set the trigger level threshold (see “Trigger
level” on page 67) to a level well above zero volts to avoid noise inadvertently trig-
gering the laser.
Industrial trigger
input
This input is isolated electrically from the laser. This gives the laser the ability to
trigger the laser from a wider variety of equipment. The maximum input voltage
range is high, and the input impedance is considerably higher than the Coax trig
input impedance. However, this input is not as fast as the COAX trig input. Note
that the Industrial trigger voltage level is fixed and cannot be set.

Synchronization output ports
Analog pulse output The signal from the Analog pulse output is an amplified representation of the
optical signal. This may be used for detection of optical pulses, with minimum
timing jitter, i.e. for timing critical purposes.
The signal is a positive analog signal from 0 to 2 V and corresponds to the
electrical specifications shown in Table 12. The signal rate matches the
configured pulse repetition rate set in CONTROL or using the front panel. The
trigger output pulse is transmitted prior to the optical pulse emission. The timing
advance between arrival of an analog trigger pulse and the optical pulse is
illustrated in Figure 54.
The advance is brief, but useful for obtaining notification of the next emitted
optical pulse. The actual total advance can vary and is dependent on the final
application setup, where the length of the trigger cables versus the actual total
optical path length can shorten or lengthen the advance time.
