RF Explorer is a handheld digital spectrum analyzer, aimed to provide a very affordable tool for work in all ISM popular frequency bands. It is based on a highly integrated frequency synthesizer which offers high performance, compact size, low consumption and low cost.
It has been designed to be used outdoor and indoor, and works nice with a PC connected for extra functionality using standard mini-USB 2.0 connector.
