FADC 125
Gerard reported on the status of the 125 MHz FADC board. See his report above for more details.
- Testing using eval boards from manufacturers.
- Input from signal generator and from ASIC.
- Using one of two channels on eval board.
- Response with 21m cable looks good.
- 28 nsec peaking time.
- Cable temperature has noticeable effect.
- Full width about 90 ns with 5 10**4 gain, t0=1.38 ns.
- Tail cancellation can be improved.
- Noise as expected, dominated by preamp instead of ADC, gain dependent.
- Good common mode noise rejection.
- All indications concerning the full board are good.
- Behind on full board delivery, but now expect to start fab by beginning of Oct.
