SDR-4000 Software Defined Radio
USB 2.0 platform for Software Defined Radio development. The SDR-4000 uses a front-end capable of 0-800Mhz operation. This small form-factor board includes a large Xilinx FPGA with a complete dual-tuner design. The dual-tuner design allows streaming both wide and narrow band conversion data from the USB endpoints. With the MATLAB-based software application this data is presented in an easy to use graphical interface.
Set-Top Box (DirectTV)
Hughes Network Systems is very good at producing in high volume, but relatively slow at building a small number of prototypes. This is because they use the same process with all its checks and balances for both large and small design efforts. Realizing this, they contracted DSP Tools to design and build their early Direct TV set-top box prototypes.Having prototypes early in the design stage allowed their software engineers to get a head start while their hardware department designed the “official’ box. They saved several months of time to market, equating to millions of dollars of sales.
A major BioTech company contracted with DSP Tools to enhance their family of cell sorting devices known as Flow Cytometers (laser-based cell sorting machines for the biotech market). Using Digital Signal Processing and FPGA technology, we replaced a 19" rack filled with 15 analog boards (with many manual adjustments) with just 3 PCI boards plugged into a PC. DSP Tools developed firmware for the cards as well as a device driver that interfaced the hardware with the Customers' LabView-based Application. The DSP firmware set a benchmark for cell processing time over previous and competing products.The new design saved a significant amount of manufacturing cost while improving the system performance by an order of magnitude. We supplied BD with tested boards for their final production. They could simply treat the board set as a purchased part.
Signal Generator
DSP Tools designed a flexible DSP-based communication signal generator for use in testing Signal Intelligence systems. The signal generator used DSP and PC software to simulate more than 100 communication signal and data protocol types. In addition, a custom-designed T1/E1 interface card allowed these signals to be inserted in a TDM stream.
Demodulator
SAIC contracted DSP Tools to design a DSP-based signal analysis system capable of demodulating any of the standard modem signals (in DSP software) up to the trellis coded V.32 QAM with its 128-point constellation. The system also provided FAX intercept and display. The front-panel GUI system handled 8 real-time channels.
Communications Solutions, Inc. chose DSP Tools to design a DSP and FPGA-based High Frequency receiver on a PCMCIA card. The design included DSP and PC software to provide a real-time display of the entire HF spectrum. The user can click on a signal and the DSP begins demodulating it and sending the audio to the PC sound system. The software can also record the spectrum directly to the PC’s disk for later review. The entire package was distributed cleanly using InstallShield. The customer again could treat the deliverable as a purchased part.
We designed the DSP TOOL signal analysis package using MATLAB, a powerful analysis package that allows detailed views of captured signal data.
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. 
To provide a control system for a UAV helicopter, DSP Tools partnered with Applied Micro Design to develop a miniature DSP-based autopilot about the size of a credit card for Allied Aerospace Industries.
Ocean Drift Buoy
For Pacific Gyre, Inc. and the University of California at San Diego we developed a DSP board for use in ocean drift buoys for processing acoustic hydrophone signals.
Airline 'Seat-Back' TelephoneFor
Hughes Network Systems we developed a prototype for a seat-back telephone system for commercial aircraft.
DSP Evaluation Board
For Wyle we developed an evaluation board for a Texas Instruments TMS320C2xx DSP. Along with the board we supplied software tools including an assembler.
