For monitoring the AOM Driver Signal is duplicated on this port.
The AOM-Monitor output is optimized for an output impedance of 50 Ω. Shortening the output may
lead to irreparable device damage.
The AOM-Monitor output is optimized for an output impedance of 50 Ω. For other output
impedance values the voltages are not correct.

Connector:
Input Power:
Pulse Repetition Rate: max. 200 MHz
An optical pulse at the Trigger input increases a counter until a software pre-set value is reached. Then a TTL-
pulse is emitted at the AOM-output. The AOM-output pulse will have the pulse width and delay which was
pre-set using the software. The counter will be set back and counts again following the next Trigger input
pulses.
