Haasoscope Pro is a full redesign of the original Haasoscope—a successful Crowd Supply campaign from 2018—which was the first open hardware real-time USB oscilloscope. The new Pro version increases the bandwidth from 60 MHz to a whopping 2 GHz, the resolution from 8 to 12 bits, and the sample rate from 125 MS/s to an impressive 3.2 GS/s.
It’s the first open-source, open-hardware, affordable, high-bandwidth, real-time sampling oscilloscope. And just like with the original Haasoscope, you can flexibly combine and sync multiple Haasoscope Pros to interleave ADCs for a sample rate of 6.4 GS/s, or for additional channels.
Normal 10x passive oscilloscope probes are limited to under ~350 MHz of bandwidth. To unlock the full bandwidth of the Haasoscope Pro, this project also includes an inexpensive 2 GHz bandwidth active probe. Unlike professional models which sell for top dollar, Haasoscope Pro is designed to be affordable, made with standard PCBs, off-the-shelf components, and an open-source design.
The oscilloscope is an indispensable tool for designing, testing, repairing, and learning about electronics. With its large bandwidth, the Haasoscope Pro will finally let hobbyists, designers, technicians, researchers, and students explore the world of high-frequency electronics, affordably. As any electronics enthusiast would understand, having an oscilloscope as capable as this on your bench is simply a dream come true.
Electronic parts that produce fast signals are inexpensive and commonplace. Microprocessors and even low-end FPGAs often have outputs with rise times of 500 ps or less. Standard protocols like USB 2.0, DDR3 RAM, HDMI, Ethernet, etc. all use signals with rise times of about 250 ps. Even simple digital logic chips can have 200 ps rise times.
Until now, users of devices and protocols such as these have been unable to see these signals accurately, unless they were lucky enough to get their hands on $20K of test equipment. A typical high-end consumer oscilloscope with 350 MHz of bandwidth can only see signals with rise times >1000 ps. (Recall that rise time ~ 0.35 / bandwidth.) Haasoscope Pro can get down to a 250 ps rise time (or 175 ps with two Haasoscope Pros using oversampling). Signal integrity can be validated, length matching between pairs can be measured, etc. You can also directly see RF signals up to 2 GHz, opening up the UHF, 433 MHz, 915 MHz, and even L bands.
Haasoscope Pro is fully open hardware, running open firmware, and uses open-source software. All hardware and firmware files are available on GitHub.
Additionally, design files for the Active Probe are accessible to anyone who wants to modify or study the design.
