N93B

Dual Timer

Datasheet

Home Modular Pulse Processing ElectronicsDigitalTiming Units N93B

Photo of N93B
  • Dual triggered gate generator

  • Manual or pulse triggered START (NIM or ECL input)

  • Monostable (retriggerable) or bistable operation

  • NIM and ECL output pulses from 50 ns to 10 s

  • Manual or pulse triggered RESET

  • (NIM and ECL) END-MARKER output pulse

  • VETO input

The CAEN Mod. N93B is a one unit NIM module housing two identical triggered pulse generators.
The module produces NIM and ECL pulses whose width ranges from 50 ns to 10 s when triggered. Output pulses are provided normal and complementary.
Timers can be re-triggered with the pulse end marker signal.

The coarse adjustment of the output width is provided via a 10-position rotary switch, the fine adjustment can be performed via a rotary handle.
The trigger START can be provided either via an external signal or manually via a front panel switch.

    Packaging

    1-unit wide NIM module.

    START signal

    2, NIM and ECL, leading edge sensitive. Minimum FWHM 5 ns

    VETO signal

    1, NIM input. disables the START input (within ±2 ns of START leading edge)

    RESET signal

    1, NIM signal. Minimum FWHM: 15 ns

    Outputs

    Two normal independent, one complementary NIM level and one ECL

    Output width

    50 ns to 10 s in 9 decade steps, with a potentiometer and locking dial for fine adjustment

    Dead time

    Shorter than the cycle time. The timer can be triggered well before the end of the timing cycle

    Rise/fall time

    < 2 ns

    I/O delay

    Delay from Start to leading edge of output, or from Reset to trailing edge, is approx. 13 ns

    End marker

    NIM and ECL output, 15 ns FWHM output pulse leading edge is coincident with the trailing edge of outputs within 2 ns
