V785

The Mod. V785 is a 1-unit wide VME 6U module housing 32 Peak Sensing Analog-to-Digital Conversion channels. Each channel is able to detect and convert the peak value of the positive analog signals (with >50 ns risetime) fed to the relevant connectors. Input voltage range is 0 ÷ 4 V.
The outputs of the PEAK sections are multiplexed and subsequently converted by two fast 12-bit ADCs (5.7 µs for all channels). The integral non linearity is ±0.1 of full scale range (FSR), measured from 2% to 97% of FSR; the differential non linearity is ±1.5% of FSR, measured from 3% to 100% of FSR. The ADCs use a sliding scale technique to reduce the differential non-linearity.
Programmable zero suppression, multievent buffer memory, trigger counter and test features complete the flexibility of the unit.
The module works in A24/A32 mode. The data transfer occurs in D16, D32, BLT32 or MBLT64 mode. The unit supports also the Chained Block Transfer (CBLT32/CBLT64) and the Multicast commands.
A 16 ch. flat cable to LEMO input adapter (Mod. A385) is available for the Mod. V785 (one 32 ch. V785 requires two A385 boards). The board supports the live insertion that allows inserting or removing them into the crate without switching it off.
