Pulse Instruments' PI-3105 A/D data acquisition system is designed for testing analog imaging devices with multiple outputs. The system features programmable gain, global offset control, and strobe and CDS timing on a per-channel basis. The 14-bit/10-MHz A/D modules can be removed for optimized speed and resolution. The analog components are electronically isolated from the digital section for low-noise performance. The scalable system offers one to 32 channels of signal conditioning and A/D conversion, and the digital data is multiplexed for efficient use of data acquisition channels. It is suitable for astronomy, military and industrial imaging applications.
