MODEL V880
SYSTEM TIMING
VME MODULE
The V880 is a VME-based system timing module, used to distribute picosecond-precision timing pulses across physically distributed facilities. The V880 receives a 155.52 MHz (OC3 rate) fiberoptic master timing signal and outputs eight local triggers. A typical facility timing system would consist of one master optical signal generator, fiberoptic fanouts as needed, and several to hundreds of V880 timing units.
  • Eight output channels, isolated electrical or 850 nm optical fast-rise pulses
  • Each channel may be programmed to respond to selected data fields in the fiberoptic master timing signal; this allows both periodic and single-shot triggers to be defined for an overall facility or for selected subsystems.
  • Each channel is equipped with a 3-second range, 1 picosecond resolution programmable digital delay generator
  • Typical jitter is below 4 ps RMS averaged over one minute
  • Typical drift is below 1 ps per degree C, 10 ps per day
  • Standard single-wide, 16-bit VME module with fast dual-port memory interface and onboard microprocessor

Test features include:

  • LED indicators for VME access, phaselock, trigger
  • Electrical test trigger input
  • Reference pulse output
    Analog output-signal monitor
  • VME monitoring of optical power level, phaselock status, temperatures, error statistics

Master fiberoptic timing signal generators are available
