mesytec MTDC-32 is a
fast high resolution time digitizer. It is internally realised as a 32 + 2 channel time stamper
(32 channels + 2 triggers). It can be operated like a traditional TDC with a start signal (at trigger inputs) and 32 stop signals, so needs no further synchronisation. Due to the internal time stamper design, the start trigger can be shifted in time by ±16 us, so no external delays are needed, even when a delayed experiment trigger is used as start signal. A pure time stamper mode allows to output all 34 digitized input signals independently with 46 bit time stamp.
Features
- 32 + 2 channel time stamping TDC
- Channel to channel or trigger to channel TOF resolution
- typical 5 ps maximum 10 ps rms
- Conversion time 160 ns
- Two operation modes:
- start-stop mode with configurable window of interest and 16 bit conversion output
- time stamper with 46 bit time stamp
- High quality conversion with very low INL and DNL
- 48 k (32 bit-) words multi event buffer
(1 word corresponds to 1 converted channel)
- Channel inputs configured by Jumpers:
- differential: ECL, LVDS, and LVPECL, terminated or unterminated
- unipolar: register configurable threshold, NIM, TTL or analogue signals possible.
- Supports different types of event synchronisation
stamping (based on VME-clock or external clock)
- Independent bank operation
- Multiplicity filter, selects events in specified
multiplicity range
- mesytec control bus to control external mesytec modules
