  • Six programmable FSRs: 100, 200, 500, 1000, 2000 and 5000 ns
  • 12 bit resolution
  • Common START operation
  • Conversion time: 2.5 µs per channel
  • Common STOP imput signal
  • Full scale time up to 5 µs
  • Zero suppression
  • Sliding scale for DNL improvement

The Mod. C414 is a single width CAMAC unit housing 8 independent 12 bit time-to-digital conversion channels. The full scale time can be selected from 100 ns to 5 µs via internal DIP switches.
The time resolution ranges from 25 ps to 1.25 ns (respectively for 100 ns and 5 µs full scale time range). The INL is lower than ±4 counts, the DNL less than ±1.5 %. The conversion time is 2.5 µs per channel and it is reduced to 1.5 µs for overflow channels. A CAMAC LAM is generated (if enabled) at the end of the conversion.
