Rockwell Collins, Inc. contracted DSP Tools to design a DSP board with an Ethernet interface and software to analyze the outputs of a high-speed Scanning Receiver. With an embedded ethernet TCP/IP stack, this system was capable of stepping a high-speed receiver rapidly while FFT-ing the sampled signal, maintaining histogram and signal characteristics from scan to scan, and forwarding the results to the users' GUI. It was capable of taking large snapshots of 8Mhz complex samples, as well as playing back down-converted samples through its on-board up-converter using a selectable IF.

A separate audio input allowed sampling from a 'set-on' receiver so that 'live' audio could be streamed over the network. Companding algorithims were also supplied.

Downloading of firmware updates could be done over the network.

Being able to run without interruption for unlimited periods was essential. The board was run through vigorous environmental testing, and the firmware met rigid government 'acceptance test' criteria.
