RF Explorer

RF Explorer spectrum analyzer with USB port

The RF Explorer is a portable spectrum analyzer. The backlit LC display shows a section of the radio spectrum and the receivable signals. Signal strength is shown in dBm or dBµV. This way you can see available signals in chosen frequency range at a glance. This makes the RF Explorer a very useful measurement instrument as well an effective bug hunter to easily find hidden transmitters.

The RF Explorer has a frequency range from 0.05 to 6100 Mhz, depending on model. This covers all important radio ranges that are used for surveillance cameras, mini transmitters, WLAN, emergency services radio and many other services. Two different antenna inputs (one on Model 1 GHz) for various frequency ranges allow for the use of specially adapted antennas that make the RF Explorer even more sensitive. A marker on the LC display indicates the level of the strongest signal automatically.

Center frequency and displayed spectrum are easily adjusted in the menu, as well which antenna input to use (on models 3G and 6G). The display can memorize and display received maximum values. This means you can leave the receiver unattended for a while and check later if a signal was received. A special Wifi mode allows for detailed monitoring of channels on 2.4Ghz Wifi (on models 3G and 6G).

The USB port of the RF Explorer is used to charge the internal Li-Ion battery (1000mAh) and to transfer data to a PC or MAC computer. With the help of freely available software the received signal spectrum can be displayed on the computer and saved for documentary purposes. The Software is open source, the USB port transfer protocol is documented, too. This makes the RF Explorer very open and perfect for hackers and hobbyists, who want to implement their own ideas. Also, firmware updates are applied via USB.

RF Explorer Signal Generator bis 6000 MHz

RF-Explorer Signal Generator

Finally an affordable Signal generator with a frequency range of up to 6 GHz becomes available. The RF-Explorer signal generator (RFE6GEN) is fully programmable and prodices signals between 23.4 and 6000 MHz, the output level ranges from -40 to 0dBm. The signal is produced either as a constant carrier (CW) or as a sweep signal between two corner frequencies. Due to the small size and built-in rechargeable battery the RF-Explorer Signal generator is extremely well suited for portable use in the field.

In conjunction with the RF Explorer Spectrum Analyzer and the free Windows software you can set up a full spectrum analyser. The signal generator is then used as a tracking generator for the specturm analyser to do four-pole measurements on cables, filters, amplifiers and much more. An open source version of the software is available on the website of the manufacturer. The connection to the computer is done via USB, the signal generator has a Mini-B USB socket. The serial control protocol is documented, enabling you to write your own software for special measurements tasks. The Windows client software works with Windows XP/Vista, Win7 and later, both 31- and 64-Bit versions.

Here is the suitable RF-Explorer Spectrum Analyser.

SMA Male/Female Adaptor

All RF connectors wear with use. The RF Explorer SMA ports are subject to minimal wear each time the connector interface is coupled and de-coupled with an antenna, a SMA cable, an attenuator or a RF device of any kind. If you repeat plug/unplug operations over the RF Explorer SMA port hundreds of times, the SMA port may underperform over time and exhibit undesired attenuation.

To protect the SMA port for frequent plug/unplug operations, you can use this adaptor and keep it directly attached to the RF Explorer port. Then you plug/unplug other RF devices into this adaptor, not the original SMA port. After hundreds of operations, if the adaptor wear and show attenuation or reliability problems, you can just replace it by a new one and always keep your original RF Explorer SMA port intact.

RF Explorer Near Field Antenna Kit New

RFE-NFAK

RF Explorer Near Field Antenna Kit is a collection of high performance set of 4 antennas designed for the most demanding RF diagnosis tasks.

  • The set contains:
  • RFEAH-25 – 25mm H-Loop
  • RFEAH-15 – 15mm H-Loop
  • RFEAH-5 – 5mm H-Loop
  • RFEAE-10 – 10mm E-Field

The three magnetic H-Loop antennas are very sensitive, compact and easy to use antennas for all sort of radiation sources. As the antenna diameter gets shorter, the antenna increase spatial resolution at the cost of some sensitivity loss; you should select RFEAH-25 for best sensitivity with connectors, large ICs and isolated signal traces, whereas RFEAH-5 works best for very narrow selective work in a populated PCB with close-by signal traces. RFEAH-15 is a good in-between compromise.

The electric field RFEAE-10 is offers a remarkable spatial resolution to determine the exact component in the PCB causing a problem, no matter how small it is.

The low loss design of these antennas exhibits at least 10dB more sensitivity than other near field antennas in the market, at a much lower cost.
Compared with other near field antennas, RF Explorer are smaller and lighter, exactly what fits best when space is constrained in a PCB.

Included with the antenna is high quality semirigid RF cable; this cable works as the handler of the antenna. The big advantage of this approach: you can shape the cable the way you want for the antenna to be located exactly where you need it, in most cases with no need to hold it in your hand.

The RF cable is coupled with a fast, easy to use SMA Push-On adapter so the different antenna models can be easily plugged in/out as required for the task. There is no need to deal with SMA nuts, just plug-n-play antennas.

  • Features:
  • Robust calibrated near field low cost 3x H-Loop and 1x E-Field antenna
  • Can work with RF Explorer Spectrum Analyzer, Signal Generator and other RF instruments and devices
  • Easy to use, reliable to find interference sources with high accuracy and resolution
  • Can be used to detect hidden bugs and transmission sources with remarkable spatial resolution
  • Feasible to generate interferences with Signal Generator and confirm RF circuit sensitivity
  • Capable of pre-EMC compliance tests
  • Include semi-rigid RF cable with coupled Push-ON SMA for easy operation and antenna selection
  • Protected by custom-designed, wooden box case with quality foam protection inside.
  • High frequency RF SMA Male-Male cable included
  • SMA Push-On adapter included
  • RoHS compliant
