The margin is insane. --- End quote --- No. You guys are inventing reality on the go :-DD Distributors do not buy for lowest possible price OEM can agree upon. https://www.ebnonline.com/shedding-light-on-electronic-component-pricing/# |

Rumor has it that some manufacturers will ask different prices depending on the market you are from. They may sell cheaper in China to compete with Chinese alternatives and recoup it by asking more from those not willing to try Chinese alternatives. |

sorry gais your mass order hunt is moot from my eyes from wherever you can get them. lets say you can find a $1 1GSps ADC in 10K qty later on... who want to play R&D with 10x $100+ ADC? ADC081000CIYB (assuming its in stock) 10x128-LQFP in interleaved trick? thats just the ADC. and what DSO/RF TEA are you going to verify them with? i know some may have a brilliant idea of using the venerable ADC used in DS1054Z to get 10GSps from 40x overclocked 200MSps to 250MSps system... ADC08200CIMT it doesnt look too much saving by any stretch there, for the sole R&D purpose. and aligning 40 x 24-TSSOP is going to be more fun, esp the 40x interleaved signals. i'm sorry if it looks like an insult but i'm just giving my (bad) idea here, i'm trying to help with the least appearance damage to the end product, and the least moral and brain damage to the interested party. but luckily, i'm very bad at giving advice in this kind of field. maybe another (worst) advice is... ASIC ADCs? with biasing and adjustable attenuation built-in? :P ... :scared: |

These proposals always end up discussing logistics of how to source cheap parts, and how to get a decent plastic case that doesn't look horrible and doesn't cost $10k for tooling. As a Open Source type hobbyist, I wouldn't mind paying for a "some assembly required" kit, but quite obviously I would expect to save some money vs say a Rigol DS1054. If you are talking about a commercial quality scope in a nice box that engineers at SMEs would buy, you are talking about a startup company attempting to compete with low cost Chinese suppliers, which has no hope in hell. Also, the idea that an Open Source ASIC would enable companies to create low cost scopes, that is rather fanciful. Anyway the two questions I would try to answer: 1) Can I make anything for $200, that would be better/cheaper than a commercial scope? (Ready to use in a box, excluding markup and shipping). 2) How much would it cost to make a decent entry level scope electronics that anyone would buy, even if just to say they have an Open Source scope? There was a reference earlier to Open Logic Sniffer, that project is dead/closed, probably killed by the $5 Saleae logic clones. |

Part costs are completely irrelevant at this point as the engineering effort in the software dwarfs any effort needed for the hardware. A project starting with looking for the cheapest parts never ends well (or never ends at all). --- Quote ---As a Open Source type hobbyist, I wouldn't mind paying for a "some assembly required" kit, but quite obviously I would expect to save some money vs say a Rigol DS1054. --- End quote --- I don't think an open source project should aim to compete with low cost equipment. The advantage should be in having an open software platform which people (companies) can extend and build upon. FPGAs fit much better in such an approach than a fixed function ASIC. One of the big features missing from oscilloscopes is the ability to extend the features by writing plug-in modules. Nowadays every manufacturer is implementing the same feature from scratch. That is just idiotic and a complete waste of time. |
