Bustec 3808 - Compteur 8 voies 100 MHz

8-Channel, 100MHz Counter/Timer/Frequency Meter

The ProDAQ 3808 function card, an enhanced version of the ProDAQ 3806 counter/timer function card, is designed to operate in one of three modes: pulse counter, frequency meter, or time interval counter. In the pulse counter and frequency measurement modes, users can process incoming signals of up to 25 MHz on each of the six channels. A time interval counter range is divided into six sub-ranges, covering times from 40 ns to 20000 s with a maximum resolution of 10 ns. For pulse-width measurements, the same ranges apply.

Every channel of the ProDAQ 3808 function card has two different counters; a 32-bit pulse counter and a 24-bit time interval counter, providing simultaneous operation as a pulse and a time-interval counter. The time-interval counter can count consecutive time intervals and store the results in an onboard FIFO memory. This allows for time-interval averaging, resulting in increased time and measurement accuracy. Users can store up to 128 time values per channel in the onboard FIFO, and perform on-the-fly readouts during the measurement cycle. The pulse and time-interval counters are globally enabled by the gate signal. In addition, the trigger signal (common or separate for every channel) can be used to gate the time interval measurements. Input signals can either be DC or AC-coupled with 1 MΩ or 50 Ω termination. Every channel has a 10-bit digital-to-analog converter, to set a threshold within the full-scale input signal range of ±5 V.
