This FFT development board from RHDC
Services features a fully functional
audio band spectrum analyzer
for just £59.95 ($95.35). An ultra low power Sharp 96x96-pixel display and judicious
selection of processor and peripheral components yields a module that consumes only
3 μA in a static state and 1.3 mA while FFT'ing. Per their website,
"The FFTD1A can typically display an image and maintain a real time clock using
less than 10µW. Assuming a CR2032 coin-cell delivers 200mAh, that's around 6 years
battery life." FFT Designer
software together with the FFTD1A development board allows users to develop application
software that performs Fourier analysis with a 12-bit, 200 ksps input and a 50 dB
SFDR. Add a simple mixer, LO, and filter to extend the useful range to just about
any frequency band. RHDC Services also provides RF R&D and communication systems
engineering services.
