I have a recollection that some 4000Bs can be liberated to 1GHz if they have the right hardware.

can anybody confirm? even upgrade to 500MHz is good. there is no official lupgrade option in the datasheet
but since MDOs had BW upgrade I though DPO4000B probably have it too

Have you tried it? It’s as simple as running gen.py with the right options to create the option key.

no I dont have the equipment. I have the opportunity to buy a 100MHz version for a good price
but I only want to do it if the BW upgrade is possible

There’s a semi cryptic note here

umm...yeah. that's for MDO4000B though but I guess they are very similar to DPO4kB at least they dont have official BW upgrade option in their datasheet just like DPO4kB.
But I wonder what he meant because I cannot find that method he is talking about
