Display is normal on Windows 10. I'm not sure how the Linux OS version could make any difference, can you post a screenshot of the whole REW window with the incorrect display? The image you attached only showed the graph and all was normal.
Maybe I was too hasty in reporting the error, I repeated the test on the raspberry but now the error no longer occurs and everything seems to be correct. The displayed value is 10.0 ohm, previously 3.17 ohm was reported despite the graph being correct.
I apologize for the wrong report, next time I will carry out more tests before reporting anomalies.
Previously the graph was correct but at the bottom the value reported next to apr 2 was 3.17 ohm instead of the correct value 10.0 ohm.
If the problem is repeated I will try to report it better.
