| May 25 at 3:56 | comment | added | Fabio Barone | Question 2: please show the following scope images using x10 probes in all cases: two channels captured simultaneously: A: CH1= TX0_i, CH2=TX1_i. B: CH1= TX0_o, CH2=TX1_o. Question 3: how many channels on your scope? Please include a photo of your entire work bench, showing the test equipment available to you. | |
| May 25 at 3:46 | comment | added | Fabio Barone | For the last two scope images: is the "fuzziness" due to noise or unstable behaviour? You can get a better idea by zooming in (faster time base). If the waveform is repeating (the image is relatively stable when triggering is continuous) then it is likely to be unstable behaviour. If the image is still fuzzy, ie: the image is not repeating then likely to be noise. Suggest also get single-shots ie: trigger just once. | |
| May 24 at 21:38 | comment | added | Ishmael | @Tyassin I disconnected C2 but no luck... No change in the signal. | |
| May 24 at 20:27 | comment | added | Tyassin | Could you try and disconnect C2? | |
| May 24 at 20:16 | comment | added | Ishmael | I moved all the wires around while watching the signal. They are all coax shielded cables. No effect on signal from moving them. | |
| May 24 at 19:49 | comment | added | BeB00 | you have long wires all over the place - does anything change when you move the wires around? | |
| May 24 at 18:49 | comment | added | Ishmael | @BeB00 Hey thanks for responding. I have included a better picture of the schematic as well as some more pictures for clarity. | |

| May 24 at 18:15 | comment | added | BeB00 | @Ishmael do you have any capacitance on your power rails? Also, a clearer schematic would be helpful (its impossible to read most of the text) | |
| May 24 at 17:58 | comment | added | Ishmael | @AndrewMorton Thanks for your reply. I have edited the above post and included more information to help. | |

| May 24 at 17:30 | comment | added | Andrew Morton | Could you use a 10x probe, show us the input signal, and show us where the probe tip and probe ground are, please? What are the differences between a x1 and a x10 osciloscope probe | |
