Joerger Enterprises VTR10012 Eight Channel, 100 MHz, 12 Bit VME Analog Digitizer with Oscilloscope Characteristics

The Joerger Enterprises VTR10012 is an eight-channel, 12-bit VME analog digitizer operating at 100 MHz sampling rate per channel. Designed for high-resolution, high-bandwidth data acquisition in VMEbus systems, this single-width 6U module delivers simultaneous sampling across all channels with oscilloscope-grade performance. The VTR10012 combines 2M samples total SRAM (256K per channel), low crosstalk below 1 LSB, and flexible triggering modes including Pre/Post Trigger and Multiple Post Trigger configurations. Individual channel filtering on analog ground and power lines minimizes noise, while 32-bit real-time trigger arrival timestamping with 10 ns resolution enables precise event correlation. Signal averaging from 2 to 128 samples improves SNR for demanding applications. Extended VMEbus addressing (A32) supports efficient 2-channel readout over D0-D31, with 64-bit MBLT64 capability for accelerated data transfer. The module operates at just 13 W, reducing thermal load in VME crates.
