We offer two solutions depending on your application requirements and budget:

SpectraPLUS-SC works with low cost Windows compatible sound cards.  Two channels of signal analysis are supported with up to 200 kHz sampling rates at up to 24 bit precision.  A wide collection of analysis tools and plots are available depending on your needs.  High quality sound cards are readily available that offer vast performance improvements over the built-in sound cards on most computers.

SpectraPLUS-DT works with the Data Translation line of USB Data Acquisition modules.  Up to 16 channels of acquisition and analysis with calibrated input levels, IEPE power, AC or DC coupling, and sampling rates as high as 2.0 MHz!  Data Translation offers a complete line of modules from low cost to high speed and high performance.  Click here for more information on the Data Translation hardware.

"I have used Spectrum Analyzers for nearly 35 years and SpectraPLUS for nearly 10 years; it is among the best. Intuitive and easy to use, it is virtually indestructible - a very stable software platform. While more expensive than other packages its reliability and capabilities make it well worth the money. This software is not a toy and stands up to the needs of the sound professional in their day to day measurement requirements." - Dr. Earl R. Geddes, GedLee LLC
