DT993 Dual Timer


DT993 is a Desktop module housing two identical triggered pulse generators.
The module produces NIM/TTL (NIM/TTL selection is performed via an on-board switch) and ECL pulses whose width ranges from 50 ns to 10 s when triggered. Output pulses are provided normal and negated. Timers can be re-triggered with the pulse end marker signal, a short pulse occurring at the end of each output pulse.

The coarse adjustment of the output width is provided via a 9-position rotary switch, the fine adjustment can be performed via either 10 turn dial handle (with lock) or by providing an external voltage.
