Protocol analyzer for IR and RF

Posted on Wednesday, December 19th, 2012 in infrared, RF, software by the machinegeek

We stumbled across this protocol analysis software aptly named Protocol Analyzer. “The Protocol Analyzer is a small tool that can catch, analyze and decode “slow” pulse based protocols. Typical examples are IR-Remotes or RF-Remotes. It uses the microphone input to read the signals. Since this is almost always available with drivers across operating systems, this tool works without any specific drivers on Windows, Linux and OSX.

Protocol Analyzer can decode a number of standard protocols such as the infrared protocols: RC5, RC6, Pioneer, JVC, Nexa, X10 and Pronto but the primary task of Protocol Analyzer is to aid in decoding new protocols. It behaves like a combination of an oscilloscope and a logic analyzer specifically aimed at analyzing digital protocols via the microphone input.”

You can download Protocol Analyzer from the project homepage. The online manual can be found here.

    You say this is open source, do you have a link to the source code?

    @Dexter, Who said this is open source? I don’t see that proclamation on the DP post, and after looking at the project and downloaded files, the project does appear to be closed.

      Well some later editing of the post after I also went to the site to try it out makes me look like the fool! The original poster and or editor should come clean and state when edits are made after the fact, Its just polite.

      The software crashes on startup on my Fedora17 system so I thought, Hey I can at least look at the source of the fault, but no its all closed and I dont fancy any java reversing right now may be later :-)

        Hi Dexter,

        Hmmm, I wouldn’t think DP would edit a post to removing an erroneous reference to open source that was corrected in the post comments without leaving a comment afterwards. Anyway, no matter…

        This thing runs OK in WinXP SP3+. It crashed in Ubuntu 12.04 LTS. I think Ubuntu is using something other than the Oracle JavaRTE; perhaps OpenJDK? I think it is the same non Oracle Java stuff that Libre Office now uses. Anyway – I’ve had a (very) few problems running Java apps in Ubuntu. Many say installing the Oracle JavaRTE fixes these problems. But the problems have been rare, so I haven’t bothered.

    With at least 2 ir capture devices out there (USB IR Widget, IR-Toy2*) which IIRC both work with the IRscope2 software (which is based on IR Widget)… anyone know if this Protocol Analyzer works with either of those?

    I’ve got quite a few pesky devices with weird little ir remotes , that if I ever lost, I’d be totally unable to use the device anymore!

    *can use IR Decoder (wxPython) , WinLIRC Rx (EventGhost for Tx) application

    IR543 X10
