RF Explorer is a handheld digital spectrum analyzer covering 15 MHz to 2.7 GHz. It is based on a highly integrated frequency synthesizer and double balanced mixer which offers high performance, compact size, low consumption and low cost. I’ve been beta-testing the unit for some time now and can confirm it works well as an affordable general-purpose analyzer.
Being battery-operated (chargeable via USB), it makes a great EMC troubleshooting tool. Probably, the major disadvantage is the limited user interface, being just seven push buttons, but there is available freeware PC and Mac remote client software to run and display waveforms. The display is also limited in resolution, but for the price, it’s tough to complain too much!
