This is how it looks on my device now using the 1.0.50 firmware (performing
same calibration procedure as described above).

I think it looks better, but the 0.8.0 firmware still seems to perform the
best on my device.
I don't know if this test is the best way to verify the performance of an
individual device?

Thanks for all your work on improving the firmware.

After reset calibration, select 8mA output (CALIBRATE->POWER->8mA) and after made calibration (this mode used in 0.8). This also reduce noise on measure.

Looking at the notes you have a fix in the H4 version "-For H4 now allow 7 save slots H - fix tupo on average (now noise floor more better)" Do you recommend upgrading my H4 version from 1.0.45?
1.0.50 version fix some bugs after 1.0.45 (hang on load from empty slot in some cases)
