V792

The Mod. V792 is a 1-unit wide VME 6U module housing 32 Charge-to-Digital Conversion channels with current integrating negative inputs (50 Ω impedance).
For each channel, the input charge is converted to a voltage level by a QAC (Charge to Amplitude Conversion) section. Input range is 0 ÷ 400 pC.
The outputs of the QAC sections are multiplexed and subsequently converted by two fast 12-bit ADCs.
The integral non linearity is ±0.1% of Full Scale Range (FSR) measured from 5% to 95% of FSR. The ADCs use a sliding scale technique to improve the differential non-linearity.
The Mod. V792 offers a 32 event buffer memory, A24/A32 addressing mode, D16, D32, BLT32/MBLT64 and CBLT32/CBLT64 data transfer mode. Multicast commands are also supported.
A 16 ch. decoupling board Mod. A992 is available for the Mod. V792 to avoid ground loops and signal reflections when long flat cable (110 Ohm) connections to the 50 Ohm inputs are used (one V792 requires two A992 boards).
A 16 channel flat cable to LEMO input adapter, Mod. A392 is also available for the Mod. V792 (one V792 requires two A392 boards).
The board supports the live insertion that allows inserting or removing them into the crate without switching it off.
