Dual triggered gate generator
Manual or pulse triggered START (NIM, TTL or ECL)
Monostable (re-trigger) or bistable operation
NIM, TTL and ECL output pulses from 50 ns to 10 s
Manual or pulse triggered RESET
(NIM, TTL and ECL) END-MARKER pulse
VETO input
The CAEN Mod. V993C Dual Timer is a 2-unit VME 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 15 turn dial handle (with lock) or by providing an external voltage.

LEMO connector 2-unit wide VME 6U for Mod. V993C |
Consult our connectors reference page for technical information.
The trigger START can be provided via either an external signal (NIM, TTL or ECL) or manually via a front panel switch.
The module features also VETO and RESET input signals.
RESET is also available on a front panel switch.
The V993C is equipped with LEMO 00 connectors for NIM/TTL signals and male pin couples for ECL signals.
