This unit
The Keithley DAS-1602 is a 12-bit multifunction data acquisition board that integrates analog input, analog output, and digital I/O in a single interface card. It delivers up to 100 kSamples/s throughput with software-selectable input configurations - 16 single-ended or 8 differential channels - making it suitable for sensor acquisition and real-time control tasks. The board supports DMA-based data transfer for high-speed applications and maintains backward compatibility with the DAS-16G Series.
