      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 Nagoya NA-773 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.

      Questions and Answers

      What is the measurement range? I want to search 10 devices in a 1m^3 rack for one noise source. Would it be possible?

      Hi, the range at which you can detect the problem is dependant on how powerful the noise is. In any case a 1m^3 is very small space so there will be no problem detecting the noise. But for accurate location of the noise itself (which can be a wrong connector, cable or device) we suggest the near field antennas:

      Thank you for reply. I understand to need the near field antennas. What's the reception range of RF Explorer RFEAH-25 ? It's 25mm or bigger than 25mm ?

      <p>Interesting.... I am not sure what I am missing the RFM22 looks like a 433Mhz board, how does this measure all the way to 2.7G?</p>

      Is there a version, either available now or in the near future, that encompasses a HD color screen, perhaps with multiple markers?

      <p>Multiple markers will be available in a future firmware upgrade in the current model offering. But anyway yes, there may be a color screen unit in the future as well.</p>
