Now that [Bunnie]’s open hardware laptop – the Novena – is wrapping up its crowdfunding campaign, it only makes sense that development around the Novena project would move over to the more interesting aspects of a completely hackable laptop. The Novena has a huge FPGA on board, with 2 Gbit of very fast memory hanging off it. Also, every single signal pin of the FPGA is broken out on high-speed connectors, making for some very, very interesting possible add-on boards. [Bunnie] has always wanted a portable, high-end oscilloscope to carry with him, and with the new oscope module, he has something that blows out of the water every scope priced below a thousand dollars.

The oscilloscope module [Bunnie] is working on has either two 8-bit channels at 1 GSPS or one 8-bit channel at 2 GSPS with an analog bandwidth of up to 900MHz. The module also has 10 digital channels, so if you need a logic analyzer, there you go.

Being a fairly high-end scope, the hardest part of engineering this scope is the probes. The probes for fast, high-end scopes cost hundreds of dollars by themselves, so [Bunnie] looked for a clean-sheet redesign of the lowly oscope probe. To connect the probe to the module, [Bunnie] realized a SATA cable would be a great solution; they’re high bandwidth, support signals in the GHz range, and are rated for thousands of insertions. These active probes can be combined with a number of front ends for application specific probes – digital probes, ones for power signature analysis, and ones for capturing signals across small loops of wire.

The module itself isn’t quite ready for production yet, but by the time the Novena crowdfunding campaign starts shipping, [Bunnie] will probably be working on the next add-on module for his crazy awesome laptop.
