The Acqiris DC240 is a modular dual-channel CompactPCI digitizer engineered for high-speed data acquisition with oscilloscope-class signal fidelity. Operating at 2 GS/s sampling rate with 500 MHz bandwidth, this 6U CompactPCI module delivers simultaneous acquisition across both channels into 256 kpoints of memory per channel. Designed for system integration, it interfaces via 32-bit PCI bus at 33 MHz with data transfer rates to 520 MB/s and supports multi-module synchronization through ASBus/ASBus2 for expanded channel count.
