RF-noise from fit-pc2

Post by John »

Hello all,

Got this problem with a fit-pc2:
It generates RF-noise, or white noise from the power cable, especially around the 50Mhz.
Some observations:

-The noise seems to be radiated from the power cable
-Tried different power supplies without success
-The noise is generated whenever power is applied, even the pc is not running


Any help is greatly appreciated!

Hello,

I observe exactly the same issue, lots of rf-noise, concentrating around 50 MHz

Will try some filtering on the power cable, maybe that helps.
It is not the power supply that came with the unit, although that is a bad source of rf-noise as well.
I tried powering from battery, same issue.

Suggestions are appreciated.

Kind regards,

Ulrich

Greetings

I will appreciate some additional info about the tests.
1. Can you specify please how have you performed the test?
2. Do you use a standard or a headless setup?
3. Can you describe your application with a FitPC2 ?

Hello!

Have you found a solution to the problem? My fit-pc is still running fine, but the RF noise is also still there.
I moved the fit-pc away from my radio's, to reduce the noise, so a solution would still be very much
appreciated!!

There is no a "magic" simple solution. We will implement the fix in an upcoming revisions. Other users can post here their custom solutions, but those solutions unsupported by Compulab in any way.
