CC3351: CE compliance testing procedure

Edward Jen
Prodigy 80 points
Part Number: CC3351

Tool/software:

Hello TI,

Do you have a detailed compliance testing procedure for hosted devices - the CC3351 in particular?

I saw in one of the pictures of the test report for adaptivity that there is what appears to be a BeagleBone and the CC3351 EVB along with something running on the laptop, but no further details.

Also, I noticed that the picture of the test setup for BLE receiver blocking had the XDS110 connected, while the Wi-Fi receiver blocking had the BeagleBone connected.  Why is this?

Could you please provide more details about what firmware/software is running on the laptop and the BeagleBone? 

Thanks,

Edward

    Hey Edward,

    I don't have anything official as of yet, but there is on in the works - expected to come out by end of year if all goes well.

    I can probably get you started here though. Most of the tests being done are going to require continuous packet transmission with discrete control over channels/TXpower/Modulation. We have two tools that enable this - Radio Tool which is apart of our Simplelink Wifi Toolbox and Calibrator tool which is a Linux application that comes with the Linux SDK. I recommend Radio Tool as its GUI based and our test house was quite effective at leveraging it with the help of the User Guide that comes with the tools. This tool requires the XDS110 to bridge the PC to communicate over SWD - this is why we always advise our customers to provide test points to that interface on the PCB.

    You will have tests that will require an established connection which can only be done with a Linux host - these will be Adaptivity and DFS. These are the tests we provide the BBB for which is flashed with our SDK. Adaptivity will require some traffic generation to load the buffers and use up the spectrum - for this we recommend the Iperf3 tool which is a part of the Linux Kernel. In my experience, when the test house sees that Iperf can be used and they have the guidance for establishing a connection to the companion AP they can typically manage the rest.

    Let me know if that suffices for now after you take a look through the guides I mentioned. We are always here to help with specifics.

    For your blocking question - There is likely no technical reason for them using different platforms. I provide enough of each for parallel testing to get the quickest lead time. Its very likely that they had the BBB setup for WIFI already in use for Adaptivity and just reused for the Receiver blocking as these have similar chambers at our test house.
