With the 3d printer, we set it going over night and it gave us a descent-looking enclosure, and we sent out for more expensive prototypes in later stages. “Normally the whole thing would take months and costs thousands. “They were fanatical about shaving height off the product,” said Tong. Ideas could be tried quickly because Pico has its own 3D printer. Mechanically, the enclosure had to hug the components as closely as possible. “The screening cans were quite challenging – to make them thin and make them work, and we found someone who would make a different style of BNC – that was the only real custom part.”
“There are some changes to the front-end for fewer parts, and some parts are in smaller-sized packages – there were a lot of BGAs already,” said Tong. Cross-talk gets worse as channels get closer together,” said Tong.Įlectronically, the design is based on the original 2000 series. “We have pretty strict guidelines on parameters like cross-talk, overshoot, and gain flatness. Squeezing analogue circuitry can help performance as there is less area to pick up noise, but eventually smaller does not equate to better. When I saw it I was immediately sold on the idea, it was a product I wanted to own myself.” They kept the project secret until they had a working prototype complete with enclosure. “A group decided to see how small they could make an oscilloscope without compromising on performance. “For the last 8-10 years, our engineers have had half a day to work on anything they want so long as it is vaguely connected to being useful to the company: learning French, hardware engineers learning software, all sorts of things,” said Tong. The shrink project started unusually: as a self-imposed challenge between a handful of engineers during the firm’s weekly blue-sky time.
