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.

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.
