Hey Len,

I'm finally back home and using the DSO again - and want to update the bug / FW list on Page 1. Can you summarize any new bugs you discovered (to save me some time) - and also, have you tested the old bugs from the list to see if any of them are fixed in v.3?

Thanks,
Mark

marmad:
Well, I finally played around with the new v.3 FW and I can't say that I'm impressed.

AFAIK, the only earlier reported (main) bug they appear to have fixed is the Math Log() function - and they've made some stupid changes that don't make sense - except perhaps because they were needed for the upcoming MSO models: for example, they changed the position of some Menu selections: MemDepth and Anti-Aliasing in the ACQUIRE menu, and they've changed the font for numbers in the menus from the nice san-serif font used for the letters to some rather ugly, less-readable, squashed serif font.

They don't seem to have tackled ANY of the serious acquisition or SCPI-related bugs - thumbs down, Rigol!

Also I noticed there is a new Ethernet bug introduced in FW v.3 - any other serious bugs that people have found?

Anyway, I think it's back to v.2 for me.

marmad:
Just to confirm what Teneyes already discovered (and posted) about the new DS2000 v.3 FW - this time using I2C: the DSO can now decode within segmented memory.




Although I'm not happy that Rigol hasn't tackled some of the bugs we reported over the last months (in both v.1 & v.2 FW), the ability to finally decode segmented memory means I've changed my mind and will stick with FW v.3.

Hopefully now that Rigol has finally finished (or is very close to being finished) with the expansion of the DS2000 line (i.e. MSO2000A), they might get back to getting rid of some of the leftover bugs. The good thing about expanding the line (as opposed to completely new models) is that the same DSO bugs will affect all of the owners - so a larger user base of customers who potentially might complain about the same thing.

marmad:
I found another new feature in FW v.3 - something we've been asking them for over the last year - and although it's a baby step by Rigol, at least it's a baby step in the right direction:

The External Trigger input can now (finally) be used for a second trigger type: PULSE

This would help explain Teneyes' earlier discovery that the Ext. Trigger can now be used as a source for the counter: it seems to go hand-in-hand with adding pulse measuring capabilities.

An encouraging sign... let's hope they keep adding more triggers it can be used as a source for.

Rory:
Now it would be good if Rigol would add an external trigger input on the back of the DS1074Z.
