    • Sub-1 GHz RF Spectrum Analyzer Tool


    The MSP-SA430-SUB1GHZ Spectrum Analyzer is CC430-based reference design that can be used to implement an easy and affordable tool to jumpstart RF development in the sub GHz frequency range. More and more electronic devices include a built-in RF link.

    RF transceivers are inexpensive - but the equipment to design and debug such systems is not. The CC430-based spectrum analyzer provides an affordable development tool that reduces the time needed on expensive measurement equipment. The system is recognized as a USB device and is operated from a powerful yet simple graphical user interface that is available for free to download.

    The CC430 microcontroller that the SA430 is based on is a highly integrated system-on-chip featuring an on-board sub-GHz radio chip based on the CC1101.
