Haasoscope Pro

Basics

• An Open Source High End Oscilloscope with USB Out
• Quote: “ The Haasoscope Pro USB oscilloscope is “designed to be low cost, while maintaining super-fast performance.” While it only comes with 2 channels, the flexible design makes it possible to combine and sync multiple devices (using Cat5 cables) to double the sample rate or add more channels.

The oscilloscope works with standard x10 passive probes but a custom active probe, the Haasoscope Pro-be, is also offered. It supports the full 2GHz analog bandwidth and is priced much cheaper than similar probes.”
