WaveDREAM-B64
General purpose
digitizer with
nanosecond time
stamp
High-Speed Multi-Channel Digitizer
WaveDREAM-B64 is a general purpose, fast-digitizing
high-resolution data acquisition system
It offers nanosecond time synchronization
over 64 channels to precisely align signals
from arrays or combinations of detectors such
as Arktis noble gas scintillators, PVT plastic
scintillators, liquid scintillators, NaI crystals,
and neutron counters. WaveDREAM-B64 is
read out via a Gigabit Ethernet link.
Key features
• 64 input channels, single-ended MCX coaxial input, 50 Ohm
• 120 MSPS continuous 10 bit digitization
• 1 GSPS region of interest digitization (10 bit parallel, 14 bit
serial optional)
• Adjustable dynamic input range (from 150 mV to 1.6 V)
• Nanosecond time synchronisation between all channels
• Trigger logic configurable in software: based on digital
signal or external trigger
• Optimized to read out and synchronize input from
various detectors
