V462 (Gate Generator, CAEN)

Timer module: 100 nsec $\leq$ gate $<$ 10 sec, 2 channels, NIM outputs for gate, begin marker and end marker (-0.8V, 50 Ohm). VME: A24D16, 256B at 0x0.

If this device is used for general scans, the sample time may exceed 10 seconds. The software restarts the timer, if needed.

This timer cannot be stopped.

If this module is used with the V260 counter the gate output has to be inverted, e.g. by a N454.
