SigC32-PC/104 DSP Data Acquisition Board

This board has been discontinued. Signalogic's DirectDSP and Hypersignal software still contains legacy drivers for the SigC32-PC/104; Please contact Signalogic for more information.

The SigC32-PC/104 board combines the power of a 32-bit floating-point TMS320C32 DSP with two (2) channels of 16-bit analog I/O, up to 640k x 32 of SRAM, and boot-EEPROM site in a very low-cost package. Burr-Brown 16-bit SAR A/D and D/A converters connected directly to the TMS320C32 serial port are used to help pack the entire functionality into a PC/104 format board.

Primary applications are in the fields of instrumentation grade measurement, high-resolution control systems, radio electronics, medical systems, vibration measurement and analysis, and high-frequency acoustic and audio measurement and analysis.

SigC32-PC/104 Software Support

The SigC32-PC/104 is fully supported by Signalogic's Hypersignal®-Macro and Hypersignal-Acoustic software packages. In addition, both the board and Hypersignal packages can also be used with DirectDSP®, which offers C/C++, Visual Basic, and MATLAB® programming interfaces. Used in conjunction with the SigC32-PC/104, the DirectDSP/Hypersignal software combination provides sophisticated DSP-based instrumentation, visualization and display of waveforms, block-diagram based automation of development and test sequences, and numerous tools for all levels of DSP product, system, and algorithm development. The complete range of DSP/math functions, interactive waveform display and editing, difference equations, filter design, and real-time code development facilities offered by the software is fully active with the SigC32-PC/104. Display examples include interactive frequency domain waterfall and contour (joint time-frequency), .WAV display, pole-zero, unwrapped phase, and group delay.

Signalogic software takes full advantage of the multichannel capability of the SigC32-PC/104. Instruments can show both channels at once, and any number and combination of the two channels can be recorded and generated continuously to/from hard disk. Instrumentation includes digital oscilloscope, real-time spectrum analyzer, continuous signal generator (up to 2 channels), stimulus & response measurement, digital tape recorder, and more. The spectrum analyzer allows measurements such as transfer function (deconvolution), impulse response, and selective-band real-time digital filtering to be performed.

Additionally, the TMS320C3x DSP Source Code Interface allows real-time code to be designed, simulated and developed for the TMS320C32, and results downloaded, tested and graphically debugged in real-time with the Hypersignal and DirectDSP packages.
