The PC104P-16HSDI analog input board provides four or six precision 16-bit Sigma-Delta analog inputs, and requires no external antialiasing filters. Optimized for flexibility and performance, the board is ideal for a wide variety of applications, ranging from simple precision voltage measurements, to the analysis of complex audio signals and waveforms.
A FIFO buffer holds up to 64K channel-tagged input samples. Each of the sigma-delta analog input channels can be controlled by either of two independent sample clocks, and multiple channels can be harmonically locked together. Sample rates are adjustable from 30 KSPS to 1.1M SPS, for a maximum aggregate rate of 4.4 MSPS. The input range is software selectable as ±1.25V, ±2.5V, ±5V or ±10V.
