content: Can the Siglent SDS2074X with a bandwidth of 70 MHz be upgraded (hacked) to 300 MHz?Does it support serial decoding beyond the screen display (serial decode on entire recorded data sequence)?

content: Rigol hacks: Plenty of hacks available, some without opening the scope, some with opening the scopeSiglent hacks: No documented hacks AFAIK for the oscilloscopes (only for signal generators and for spectrum analyzers). Or is that a mistake?Rigol decoding: DS1054Z: Limited to the screen, DS2000A: Not limited to the screen (full record buffer)Siglent decoding: SDS1000X: Unknown (limited to screen?), SDS2000X: Unknown (limited to screen?)

content: Siglent have not adopted Rigol's marketing policy what include "designed for hacking".Many scopes, including Rigol do not have all captured memory lenght visible on display so you need ask how it use part of waveform what is outside of screen..In Siglent, what is captured is also visible on the screen. Outside from screen is nothing so there is nothing for decode. Period.

content: With some time bases it's almost impossible to cram everything on the screen. It is much better to use a scrolling window, like GW-Instek has implemented in the GDS2000E series, or like Rigol has implemented in the DS2000A series.

Top window is whole memory and bottom window can zoom and scroll.But, other thing is that this as all can do better and need do better. I believe development continue and I hope development is never any kind of imitating what Rigol do. Imitator can not be before who he is imitating.

content: Quote from: rf-loop on August 09, 2016, 11:53:44 amWith this remark you show you still don't understand the huge problem with 'decoding what is only on screen'. Please learn that first because it is the difference between useless and usefull when it comes to protocol decoding.

content: That would be an interesting comparison video for Dave:Comparison of serial decoding on Siglent SDS1000X, Siglent SDS2000X, Rigol DS1074Z, Rigol DS2000A,GW-Instek GDS1000B, GW-Instek GDS2000E.When the engineering manager of Siglent and Rigol will see this video, he will pinpoint his engineers to change the implementation, and do it in the same way as the GW-Instek GDS2000E.The engineering manager might even approve a purchase order to buy a GW-Instek GDS2000E for further examination in the sweat workshop
