Seeed's RF explorer line of handheld digital spectrum analyzers is available in several models to cover all the popular frequency bands from 15 MHz up to 6.1 GHz. Based on a highly integrated frequency synthesizer and double-balanced mixer the RF Explorer spectrum analyzers offer high performance, compact size, low consumption, and low cost.

RF explorers can be utilized as a standalone device or by interfacing via a standard mini-USB connector with a PC running advanced data analysis software, which is available as a free download. Software tools are available for Windows, Mac OSX, Android and Linux. With a high-capacity lithium battery and rugged aluminum case, RF explorers are designed for use indoors and outdoors. The RF Explorer will display full frequency spectrum in the band (including carrier and modulated shape), display spread spectrum (SS) activity if present, show bandwidth to monitor collisions along with frequency deviation from expected tone, and more.
