DC222 - Acqiris Transient Recorders Digitizers

Acqiris DC222 Overview

The DC282, DC252 and DC222 PXI/CompactPCI 10-bit digitizers can each achieve a dazzling singlechannel sampling rate of 8 GS/s, and offer a choice of front-end input mezzanines providing up to 3 GHz input bandwidth or switchable high impedance input coupling. This front-end flexibility, coupled with astounding data conversion performance, makes these digitizers ideal for implementation in applications such as high-resolution radar, lidar and ultrasound, as well as semiconductor test and large scale physics research experiments.

The DC282 offers synchronous four channel sampling at up to 2 GS/s, or interleaved dual- or single-channel sampling at up to 4 and 8 GS/s respectively. The DC252 and DC222 digitizers offer the same dual- and single-channel sampling performance, with the model DC222 achieving 8 GS/s on its single input channel. These digitizers are fully compliant with both the PXI and CompactPCI standards, and incorporate Acqiris proprietary XLFidelity and JetSpeed II ADC chipsets, designed for the specific purpose of optimizing highspeed ADC performance. The three modules combine this ultra fast sampling rate with standard acquisition memories of 256 kpoints (DC282), 512 kpoints (DC252) to 1 Mpoints (DC222) per channel, and optional acquisition memories to 256 Mpoints, 512 Mpoints and 1 Gpoints respectively.
