Each A/D module provides field programmable input range and gain for each channel. The ability to set lower than expected, full-scale voltage gain ranges assures the use of the full resolution. Each channel includes an anti-aliasing filter with an inherent digital "brick wall" filter and a digital second-order IIR low-pass filter with a programmable breakpoint that enables users to field-adjust the filtering for each channel. All channels have continuous background Built-In-Test (BIT). The modules also include extended A/D FIFO buffering capabilities for greater storage/management of the incoming signal samples (data) for post processing applications. Programmable FIFO buffer thresholds maximize data flow control (in and out of the FIFO). Incremental relative time-stamping between samples is also provided as a programmable option.
