Unrelated update:So SDR appears to be a great cheap alternative replacement for Spectrum Analyzer to do near-field E/H-emissions testing. Or troubleshooting interference sources as it was discovered with Nucleo STM32H7 board in this thread. After som...

Hey Matthias,I have unrelated question:You've mentioned that you use newer NUCLEO H743ZI2 (I've am using a regular ZI). Does your board has newer revision "V" of STM32H7 on it? The one that can run at 480MHz?https://www.st.com/resource/en/errata_shee...

Got my MSi.SDR delivered, so made an H-field probe to see more what spectrum is radiated from Ethernet PHY chip:Using RSP Spectrum Analyser software, here is the spectrum when the probe is far away from the Ethernet PHY chip:And this is when the prob...

PROBLEM SOLVEDAppears to be an issue of the Nucleo-144 demo-board itself (NUCLEO-H743ZI specifically), NOT AN STM32H7 FAULT!HOW TO FIX?Desolder/remove L2 ferrite bead to disable Ethernet PHY chip (see Nucleo-144 schematic, it is located close to that...

Here 2x ADC modules with 2 channles per each during simultaneous sampling each pair of channels at much lower frequecy (~13 kSPS)Basically - the range of min-max values are are the same, as at the high frequency. But you can't not see that there is s...
