Hi, Benton here, speaking from a 35+ Tek career completed earlier this year...? ?I spent my entire time there writing SW for mid-range o'scopes, starting with the 2465 and ending with the '5 Series' MSOs.
>?Siglent, Rigol, Hantek, are good places to start for low-cost new gear.
>But you don't necessarily want to buy from the lowest bidder,
There was a story, repeated by a couple folks in one of the other AR mail lists, that Tek OEM'd some of our low-end scopes from Rigol.? They were apparently told this by a rep at one of the trade shows.? (I don't know if it was a manufacturer's rep or one of the distributors.)? I thought this was untrue and confirmed it with one of our guys that would know for certain.? If anyone repeats this story to you, they've either bought in on the lie or are trying to deceive you.
> I'm not aware of any other scope for which a firmware upgrade removes a marketing gimmick like that,
some people seem to assume it's true of all the new DSO's.
This, on the other hand, is true -- many of Tek's mid-range o'scopes can increase BW at least through some steps via the application of a license key.? It might be either a fob or application of an encrypted string or signed file.? (Some models do require a board-swap to attain the top BW level.)
Back in the day, for one of our scope lines that did actually implement BW differences with HW changes (I think it was the 2220/2230 pair) the lower BW model was actually *more* expensive to build.? It included a couple extra caps on each channel to roll off the BW early.? 8*)
