content: HiJust wanted to get some opinions before purchasing a scope.Budget is <$5K4 channels is a must.Key is to buy something that benefits greatly from the hack in terms of bandwidth , sampling rate, features (ie has same hardware in cheap and expensive variations)Thanks

content: Very generalized question as the required feature set has lots to do with an acceptable selection.To 500 MHz SDS2104X Plus is hard to beat.SDS5000X models are running a free BW upgrade promo which boosts a $5,689 SDS5054X to the 1 GHz SDS5104X.

content: Normally you'd start by ask questions like "What will it be used for?", etc., before recommending anything.

content: Quote from: tautech on July 26, 2021, 11:01:57 pmSome can't zoom-out after an acquisition for example. The world is bigger than Siglent so jumping in as the resident Siglent salesman and offering no useful information at all is helping nobody.The OP should really consider use cases and then look at what is most suitable. There is no use buying a scope which can do a million things except for what the OP needs most. Likely buying several (cheaper / used) scopes instead of one gives a better coverage compared to buying 1 expensive scope. Nowadays it is easy to pick up a used >1Ghz scope for less than $1k from Ebay. With some patience you can pick up a relatively modern Lecroy (running Windows with USB ports) and hack it to get a boat load of analysis features that makes anything else out there look pale in comparison. OTOH such a scope is likely not the best choice for everyday bench use.

content: Quote from: tautech on July 26, 2021, 11:01:57 pmExactly!When you want to spend $5k on a 'scope you usually have a very specific need in mind, otherwise there's not much point in spending more than $2k.For $5k you're looking at active probes and all the rest of it. Best to get some details on what it will be used for, in what environment, etc.'Scopes in the $5k bracket generally aren't hackable Chinese 'scopes like Rigols and Siglents.If the OP simply wants to spend a lot of money on a really nice 'scope then maybe something like R&S is the way to go.Quote from: nctnico on July 26, 2021, 11:10:50 pmThis, too. For $5k you can pick up a used 'scope that cost $25,000 a few years ago. Businesses pay through the nose for cutting edge features and those devices depreciate real fast.

content: Quote from: Fungus on July 26, 2021, 11:21:04 pmI was just about to type a reply, when I noticed you just posted that.My question would be first, which scopes are hackable? Rigol and Siglent are the two I'm aware of. Not sure about GW Instek. Are there others? If the OP definitely wants a hackable scope, it greatly limits the field right there.

content: Keysight. There are topics on this forum for 1000x and higher 2000x,30p0x,4000x models.@OP depending on how high you want to step up in terms of upgrades, you may need to add hardware to the scope. Some scopes may have same PCBs as their lower priced siblings but the PCB is not populated with parts.

content: This is a unusual question...For 5000 USD you can buy fantastic scopes (new and used) that don't need hacking.Quote from: Bud on July 27, 2021, 12:47:19 amI would argue that mechanical disassembly, soldering on the board and all other kinds of equipment changing except just software changes cannot be considered "hacking" in a sense of word...I would have hard time recommending something worth 5000 USD that needs soldering and physical changes, that can easily damage it permanently, to a unknown person of unknown skillset.On Keysight 3000 and 4000, software changes that convert 100>200 and 350>500 MHz and open all options are hacks, that are easy and low risk as those on other scopes. Everything else is not for the fainthearted.But as I said, for 5000USD, you can buy a lot of scope without hacking of any sort...OP needs to explain his request better. Otherwise it's shooting in a dark....
