I am trying to use the trigger input for TTL signals to synchronize STG 4004 with a NI data acquisition system. The problem is that the logic state of 1 of STG4004 is between 2V and 3.3V, while the digital output of the NIsystem is a 5V TTL signal. I wonder if I can contact two instruments directly, or coild you please give some advices on contacting them. Thank you.

Am I getting this right, you want to use the Trigger In of the STG, and deliver a TTL of 5V to it? If so, that's no problem, the Trigger In will accept 5V. It's only that the Sync Out channels of the STG produce 3.3V TTL pulses.
