Although I will refrain from further analog bandwidth discussions until I can conduct my own tests, I will not bad mouth the Quad analog bandwidth quality, until someone performs the following:
- Loads the current firmware
- Performs the published compensation adjustments
- Repeats the sinewave bandwidth tests with at least 1Mhz steps, while looking at the ADC input with a high quality scope.
I will do this when I get my replacement Quad. Until someone does all these things, the Quad analog bandwidth is still undefined.
Beta hardware replacement discussions are only valid once it has been determined that the firmware and adjustment procedures can not fix the problems. I don’t think we are there yet. Most things “beta” carry some level of frustration, so why should this be any different? Patience is a virtue that is hard to manage, yet necessary when dealing with “beta” products.
Bainsbunch has a previous post about “lightening up”, and I have to agree with that concept, even though it now appears that “lightening up” appears to have become road kill. Seeed Studio does not control those folks who write the firmware changes, so Seeed certainly can not expedite those updates. It would be most helpful though, if Seeed would confirm when forum issues and concerns have been presented to the manufacturer for action.
By the way, all the above is just my opinion, not factual representation, and is therefore not subject to argument.
