This credit-card sized board contained an on-board DSP (Analog Devices SHARC ADSP21065L), a digital down-converter, and high-speed ADC interfaced to the PCMCIA bus. DSP Tools provided the DSP firmware, Plug-'n-Play PC Device Driver, and GUI Application software all bundled in an InstallShield distribution package.

 

The unit was capable of recording 'live' spectral and sampled data, demodulating and streaming the resulting audio to the PC speaker output. Defaulting to a Spectrum Analysis view, the operator could simply draw an outline on the signal of interest, jumping into demodulation mode automatically.

Captured data could be viewed with a provided offline analysis package, and quickly scanned for specific spectral criteria. The unit could interface to an antenna, or customer-supplied pre-selector front end (automatically detecting and compensating for the interface).

Working closely with both the customer and his client, the entire system was delivered as a 'customized-for-the-end-user' product, and the first of a family of 'Software Defined Radio' subsystems.
