content: really nice hack! To activate it on other 1xxx models will be a winner

content: NiceWas looking at his plugin to analyze DS2000 firmware, maybe a similar service mode exists.However, DSP processor is different (BF526 vs BF531). Would probably require more work than I am capable of.QuoteSo it could be completely disabled or they've added more security. I don't suppose any rigol assembly line workers read the forum?

content: There is no big difference between BF531 and BF526, you must change only the blackfin.cfg file...its a textfile with the peripheral registers of the blackfin.In the DS1052 v2.05 are some functions completly removed, so you have no chance to activate it without firmware patching. On older versions, i don't know.I'm sure it's possible to hack any firmware version of the Rigol DS1052 to make 100MHz. The only question is how. If you have the firmware, you can find a way....

content: Awesome! My DS1022C now has the 2ns timebase. If the true analog bandwidth has been increased from 25MHz to 100Mhz, I haven't been able to test this really...

content: But it still has only 400Ms/s per each channel...

content: Of course it has still the 400MSa/s. However, it is a nice unexpected software addition to a piece of hardware unchanged since I got the scope directly from China in like 2008. Well before the 1052E models became famous.

content: Hacking the 1052e is easier than ever. I did it in about half an hour with a downgrade-hack-upgrade procedure. No serial cables, just USB and a pen drive.

content: I'm a bit confused when I read that some DSOs can be hacked to gain more bandwidth.My opinion is that if someone make a DSO, say with 200MHZ bandwidth he must be crazy to sell it like a, say 150MHz bandwidth DSO. Where my opinion is wrong?

content: This has been discussed extensively in one of the Agilent DSO-X 2000/3000 threads. If the cheap DSOs use the same 200 MHz parts/design, then the R&D can be spread over a much larger volume, while maintaining the higher profit margin on higher end items.

content: Quote from: nack on May 09, 2013, 08:00:26 pmI've got my DS1022CD now with a 2ns timebase too! This is pretty cool. There have been so many times I've wanted to go smaller than 20ns!I compared a 80 MHz TTL oscillator on it and while you can cleanly see the signal, it is attenuated quite a bit (3.06V) compared to an DS1102E (5.31V) so the inputs are not 100 Mhz... No bother though, I'm thrilled to have it go down to 2ns.
