RF Explorer is a handheld digital spectrum analyzer, a very affordable tool for work in all popular frequency bands. It is based on a highly integrated frequency synthesizer and double balanced mixer which offers high performance, compact size, low consumption and low cost.


It has been designed to be used equally well outdoor and indoor, and can be connected to a PC for extra functionality using standard mini-USB 2.0 connector.


This model includes a WSUB1G baseline unit plus an RFEMWSUB3G Expansion Module conveniently assembled and tested. It comes with two SMA connectors and two antennas,a nice dual band telescopic 144/430MHz wideband telescopic antenna for all Sub-GHz frequencies and a whip helical for 2.4GHz band. Additional, specific band antennas may be needed to cover efficiently some of the frequencies supported.


The combination of these two models offer the wide band coverage of the WSUB3G module, together with the highest sensitivity and quick response of the WSUB1G model for the popular sub-1GHz frequencies.
