The pre-gating time depends on the frequency the amplifier is designed for. The lower the lower frequency of the amplifier's bandwidth the longer the pre-gating time must be. For specified values refer to the data sheet or manual.

For some models the option Fast Pregate is available. With it the minimum pre-gating time is reduced to 1 - 2 μsec.

For the blanking signal use 5V TTL level. Modifications may be possible upon request.

In most cases polarity is high active. That means you need to connect 5V to pre-gate the amplifier. However, polarity can be adjusted if necessary.
