Our engineering team has put together a short video that shows LimeRFE in action:

In this video, a LimeSDR Mini makes use of the LimeRFE software-definable RF front end to generate a swept sine wave, first across the two meter amateur radio (HAM) band, then across a frequency range within both LTE (Band 3) and GSM (1800 MHz). A simple Python script was used to configure both devices through the Lime Suite API.
