This is excellent! EMI testing is one of the things I have to do with my projects, but there hasn't been an affordable way to visualize them. I've played with an RTL-SDR for ADS-B traffic so this is right up my alley. I'll be sharing this with coworkers for sure!
- jononor 8y agoGot any resources on EMI testing on the cheap? Would be a great thing to share in our makerspace, as many do semi-professional electronics.
- xondono 8y agoIf you have a decent oscilloscope, you can actually get pretty far with that and some DIY probes.
- Junk_Collector 8y agoIt's worth noting that his bandwidth is only 2MHz on his SDR so this will require a lot of manual testing and tweaking for good EMI/EMC results. It might be useful for crosstalk but a directional probe would be better for that because you can account for trace alignment. A directional probe can be made in much the same way as his loop probe, but will be a mono-pole design and will probably require an amplifier.
