Wireless products need to perform well in the complicated and unpredictable RF environments found in the real world. Simulators can help designers up to a certain point in the development process, but they cannot mimic all the multi-path, interference and general signal degradation effects that end users will experience. Using an RF recorder to capture the spectrum segment of interest over a range of minutes to hours gives designers the data necessary to diagnose and solve problems and allows them to build up a library of environments to harden their products for the future.


Averna has released a field-ready multi-channel RF recorder for applications in the range of 330 MHz to 2.5 GHz. The RP-5300 RF Recorder is an advanced tool for both field testing and performance testing. With 50 MHz recording bandwidth and 16 bit resolution, it can record multiple GNSS signals in up to two bands (L1, L2, L5), such as GPS or GLONASS. Its compact size and integrated display make it ideal for field operation.


The RP-5300 comes preloaded with Averna’s RF Studio software, a workflow software for making RF recordings, managing collected data, and analyzing or playing back collected RF environments.
