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.

GUI Features:

Open source QT-based Graphical User Interface (GUI)

Flexible GUI allows developers to set desired frequency range and amplitude to measure

Configurable to show continuous sweep readings or single snapshots

Up to 4 traces can be visualized on the GUI, which can be configured to show maximum, average or actual readings.

Markers are available for easy measurement readings. These markers can be controlled manually using a jog wheel, or dynamic based on auto peak detection

The GUI view can be configured to show grids, customizable labels, inverted colors and other options

Screenshot capability is available to record readings as .pdf or .png file types.

Traces can be exported as comma separated file

Configuration settings for the GUI can be saved and loaded for future measurements
