content: Can anyone summarize the difference both in performance and cost between these two scopes? Anyone know when the 'A' version is due to be released?

content: According to the quote I just received this morning, the DS2072A will sell for the same price as the DS2072 and the only difference is the ability to switch to a 50 ohm input impedance. The supplier says that the DS2072 is no longer available for new orders.

content: Quote from: neslekkim on December 09, 2013, 09:50:10 pmHow much do they charge for DS2072 and DS2072A in Norway? Any online retailers?Maybe you can buy it cheaper from the German Rigol distributors? From what I've seen they are a lot more expensive in Denmark than Germany.Batronix seems to be one of the most popular German distributors (they haven't listed the A models yet though):http://www.batronix.com/shop/index.htmlBut there's other's too as you can see here:http://eu.rigol.com/html/about/Distributors.shtmlAll the German distributors seem to charge identical prices for Rigol products.

content: Do anyone know more about the signalgenerator?, the retailer here suspects its the same in the DS1000Z-s as in the DS2000A-s, but I dunno.Is it like only square, sawtooth, and such things, or is it more advanced?, Found that its lots of commands for it in the programming guide, but not easy to understand for my level

content: Suprisingly, in Russia DS2072A sells for less money (34 456 rub/1050 usd) than DS2072 (38 232 rub/1165 usd). And DS2072A-S (with SG) available for 48 970 rub/1493 usd.For the time DS2072A hardware is the same with latest DS2072 hardware. But model range goes up to 300 MHz BW instead of 200 MHz BW on non-A. And there is available software option for CAN triggering for A-model.But this is all official.In the hacker way you already can switch on 300 MHz BW and CAN trigger on non-A model (search for it) and also you can enable all software options (memory depth, decoders, triggers) for non-A version. For A-version hack is still impossible, but I think it's a matter of time when it will be.

content: Yes, i have read a lot of the info in the sniffing thread, very exiting, but it's very strange that Rigol sells unit like this, and does not sell softwareupgrades for bandwith, like Agilent does, if they did, I would be more confident that everything is *excact* the same.As for now, I'm not sure about the consequences for the LMH6518 gain amplifier that doesnt seem to get programmed when "upgrading" the scope.

content: For Norway, I know only of Venotek for Rigols. Anyone else to consider?(I'm looking to buy, and would prefer a local source if possible).As to the price-difference, Norwegian Kroner has dropped between the "old" and the A version, which likely explains the difference. Fair enough.And yes, you'd beed to pay VAT if importing one, so relember to add 25% to both price of scope and shipping when comparison-shopping.

content: Venotek it is.. I don't want to import, hell break loose if you need help with it.Venotek said they didn't know if the price on the non-a models would go down, but the price between is not that much, was more about that they infact have pricedifference whereas others have same price, oh well.Elfa have some offers on the agilents now, but I'm not sure if I want to have an winCE box..But I'm not sure yet if venotek sels to privatepersons, or only to companies, waiting for that answer now.

content: Quote from: neslekkim on December 10, 2013, 06:44:14 amI'm not sure why you're not confident, but the hardware is exactly the same across the DS2000A line (obviously with added parts for S version).Not only that, but there is absolutely NO DIFFERENCE (and never has been) - even in the firmware - between the DS2072 and DS2102 - they both have precisely the same > ~115MHz bandwidth. So if you buy the DS2102A, you are essentially giving Rigol the extra money for a different sticker on the front panel (and different model number displayed in System Info). This was confirmed a few times about a year ago.

content: Quote from: neslekkim on December 11, 2013, 02:58:11 pmIt's just a bit of firmware code which sets the LMH6518 chip to limit the bandwidth to 100MHz (and removes 2ns/div and 100MHz limit as user selections). Change the model number - or enter an option key - and you have a DS2202.All of this has been proven about the DS2000 series a long time ago (with bandwidth tests). And it follows the exact same pattern that Rigol has been using since, at the very least, the DS1000E series - of producing a single piece of hardware for an entire series of DSOs - then selecting the bandwidths by putting model numbers into internal memory - which then affects the firmware routines.

content: What I read earlier about the LMH6518 was that the information was not sendt to that chip in the hacked scopes, but maybe that was before everything was figured out?, so one know now that it's reprogrammed when using it?

content: Quote from: neslekkim on December 11, 2013, 07:33:37 pmThe bandwidth has been measured with reliable equipment already a few times on hacked DS2072s and on unhacked DS2202s - and it's the same. What other proof do you want that the hardware is identical?
