All of the example applications that we’ve shared so far have been demonstrations of one form or another of wireless communications. And, while this is obviously the main use that we had in mind for LimeSDR, it is by no means the only one and it can equally be put to use in many other demanding RF applications that require signal generation and reception or measurement.

The Lime Suite software which provides the driver for LimeSDR comes supplied with a powerful GUI that makes it possible to quickly program its FPRF transceiver, read back registers, plot signals and perform all manner of tasks that can prove invaluable when developing new applications. In a video that Juri has put together, he demonstrates how with just a few clicks this GUI can also be used to turn LimeSDR into a spectrum analyser, oscilloscope and signal generator.

More than simply one of those “because you can” exercises, using LimeSDR in this way is actually proving to be highly useful in Juri’s day-to-day work, as a conveniently compact all-in-one tool that he can use when not in the lab, or when he needs to make a quick measurement and the costly bench test equipment he would usually turn to is in use by colleagues.

The second demo that we have to share comes from Juri’s colleague, Danny. In this he shows LimeSDR being used with GNU Octave, free and open source software which provides a numerical programming language that is largely compatible with Matlab. Uses for this include more advanced signal generation and measurement, together with the prototyping of new wireless and other RF systems. In the video Danny shows WCDMA (3G cellular) signals being generated and plotted.
