James Lewis writes about the ThunderScope which features to 350 MHz analog bandwidth with 1 G/s sample rate streamed to a PC at 1 Gb/s:
Oscilloscopes can be an electronics engineer’s best friend. These highly versatile tools are helpful, from basic debug to verification tests to compliance checks for standards. Not only are their measurements varied, but so are their form factors. Two common styles are “bench” scopes, which go on a bench, and PC-based oscilloscopes, which, until now, have primarily used USB. An Ontario-based EE graduate student, Aleska Bjelorlic, is launching a Crowd Supply campaign for an open source software-defined oscilloscope. The four-channel ThunderScope has up to 350 megahertz of bandwidth and can stream acquisition data to a PC at one gigasamples per second.
Since we last covered ThunderScope, Bjelorlic and friends have further developed the hardware to a near-final state and have continued extensive work on the software side.
ThunderScope comes in an unassuming box that is just large enough to house 4 BNC connectors, a compensation output, four fully-functional front-end stages, an ADC, and an Artix-7 FPGA to capture the data and transfer it to the PC.
