Trigger Input
An electrical TTL trigger input is provided for synchronizing the Camera Beam
Profiler's global shutter to Pulsed Laser Sources . The appropriate BNC
connector is situated on the left side of the instrument body, see Connectors .
The following table summarizes important electrical data for a compatible signal
source.

Applicable safety standards
IEC 61000-4-2 (ESD 15kV air, 8kV contact)
IEC 61000-4-5 (Lightning 12A 8/20µs)
IEC 61000-4-4 (EFT 40A 5/50ns)
Attention
Be sure to enter only a TTL compatible signal to the BNC jack not exceeding
the range (-0.5 V … +6.5 V). Higher or lower voltages may damage the Beam
Profiler input!
Note
Use shielded coaxial cables for connecting the trigger source only. Do not connect a
trigger cable without a signal source because it may capture disturbing trigger
pulses.
