2. Fixed the Uart decoding error when baud rate is 10400.
3. Fixed the crash when math advanced is “CH1==CH2”.
4. Fixed storage and recall waveform error in ROLL mode
5. Fixed trigger delay in 500uV/div

what is also measured with a signal generator

It is even better. Look at the picture, there rise time is 1.32 ns which gives BW = 350 / 1.32 = 265 MHz.

That's hardly 10% to 90% rise time, more like 15% to 85% which will show a much shorter time and thus calculated bandwidth.

Updated the bug list (download links for FW at the bottom of that post):

Struck out bugs #6, #12, and #13 which appear to have been fixed.
Anti-aliasing still does NOT anti-alias.

I haven't tested the RS-232 decoding issue yet. If someone else finds that it's been updated, let me know.


On another note, I love that Rigol continues the confusing reverse downward notation of the final version number digit - hopefully next version will end with .01 or .00  ;D

Are you telling that Rigol calculates the rise time in wrong way?

Looks good, there are not many bugs anymore. I hope there are no new bugs!  :) :-+
I am not at home now, so I can not test it.
