RF Explorer is an affordable Handheld Spectrum Analyzer designed from scratch to be a sort of Swiss Army Knife for the specific needs of ISM band digital communication. Depending on the model and (optional) expansion board you'll be able to cover all ISM bands.
The iRF Explorer application connects to the device over the USB port using a normal USB to mini-USB cable.
You are then able to extract spectrums, spectrograms and capture screenshots. Furthermore simple maxima, averages and standard deviations can be calculated on the fly.
These can be exported (simple copy/paste) as a PNG, PDF for inclusion in reports; as text or Latex for use in a Laboratory Information system or as CSV files. In the latter case - a paste in Numbers/Excel will allow you to further manipulate the numbers.
For those who do not yet have an an RF-Explorer - there is a demo which uses your microphone as the source for a spectrum.
Version 1.01 - September 2011
- First version.
Version 1.07 - November 2011
- Support for RF Explorers with a second expansion cards
- Support for Lab-book/notebook auxiliary info on print and paste.
- Control over PDF v.s. TIFF/PNG copy/export for LIMS applications which do support only either format.
- Spectrogram (scrolling plot against time)
- Improved Copy/Paste and Print (including Latex and text versions of the settings).
- Support for the WiFi Analyzer mode
- Support for automatic full-range sweeping
- Audio demo mode added.
- Show the WiFi frequencies as Channel # (in WiFi Analyser mode) rather than Ghz.
- Display the standard deviation along with the average (as a spread).
- Signal strength (dBm) values corrected for narrow scales.
Fix various default settings or provide better values.
- Graph backgrounds are now really white.
- Pair down bundle details for localisation and lots of tooltips added.
- Ignore the device its power-up string; and respond to resets/hangs of the hardware or serial bus with a retry.
- Improved the X axis tick v.s. labelling as to avoid cluttering the display; and man tooltips added.
- Fix the wrong Hz scale on the maxima and the paused scaling of the live display.

Unfortunately True Reviews
Looks like to me, on the first run of this product, it DID freeze and require force quit to get rid of, as was mentioned in the other reviews. Looks like a good start to a program that will be of use, but needs some polish for the Mountain Lion Operating system.
Also I noticed that this as many other wifi discovery tools, does NOT SUPPORT external wifi cards. Yes, I know it's easy to assume that all people running this have a built in wifi card, and they do. BUT assuming that limits your product to only that. external cards allow antenna to be connected and are very necessary for pro use. As a programmer it should be pretty easy to build a little option to switch between installed hardware. I hope to see this change soon, and I can rate better on a future version.
Avoid - at all cost
Immature piece of software, I can't believe Apple let this slip through the cracks. 50% of the time it freezes upon execution. The other 50% of the time, the process dies 100% of the time when you go into the preferences. Process zombies after that, and cannot be killed unless you restart your system.
So when I tried installing the drivers nothing happened. I tried again several days later and it went through the install menu, restarted. I plugged the rf explorer in and it works! So I can verify it 100% works on mavricks.
With Family Sharing set up, up to six family members can use this app.
