Our hacker [haas] is at it again with the Haasoscope Pro, a full redesign of the original Haasoscope, which was a successful Crowd Supply campaign back in 2018.
This new Pro version was funded on Crowd Supply in April this year and increases the bandwidth from 60 MHz to 2 GHz, the vertical resolution from 8 to 12 bits, and the sample rate from 125 MS/s to 3.2 GS/s. Selling for $999 it claims to be the first open-everything, affordable, high-bandwidth, real-time sampling USB oscilloscope.
The firmware and software are under active development and a new version was released yesterday.
The hardware has an impressive array of features packed into a slick aluminum case with quiet 40 mm internal fan and 220 x 165 x 35 mm (8.66 x 6.5 x 1.38 in) form-factor weighing in at 0.9 kg (1.98 lbs). Also available is an active probe supporting up to 2 GHz analog bandwidth.
The Haasoscope Pro is miles ahead of alternatives such as this USB oscilloscope from back in 2010 and you can find a bunch of support material on GitHub: drandyhaas/HaasoscopePro.
In what universe is a 3.2 GS/s scope a 2 GHz scope?
Credibility spent.
Nyquist to the head.

Ha – yes! Got there 3.2×10^-9 seconds before me.
It allows you to daisy-chain two together via a CAT5 to get 6.4, so maybe that’s the reason behind the claim? Still a lot less than the “equivalent” Siglent. Otherwise, totally agree :)
A lot less $$, I meant to say
When “ you can flexibly combine and sync multiple Haasoscope Pros to interleave ADCs for a sample rate of 6.4 GS/s”.
HaHa never fails to disappoint. At least he’s consistent.
Consistently right.
No.
Doesn’t matter what you can do with two of them.
That’s not a qualified claim.
It’s BS.
Whoops, accidentally clicked report instead of reply.
Agreed. Saw this a few days ago, and while it’s a really cool project/product, click baiting capability runs me the wrong way.
According to the crowdsupply page linked above, the 2 GHz is ‘unlocked’ when using two scopes:
“You can combine two Haasoscope Pro units to achieve 6.4 GS/s on a single channel (unlocking the full 2 GHz bandwidth) or distribute the bandwidth across multiple channels (two channels at 3.2 GS/s each, one at 3.2 GS/s and two at 1.6 GS/s, or four at 1.6 GS/s).”
Still blows my mind that a 3.2 GHz 12 bit ADC can exist.
But Digikey is listing them for $2k (onesies, retail). How can the whole ‘scope come in at half that?
It would be nice if the video actually showed anything.
And again, still without a decent analog frontend (max 3V input in 1MOhm input mode, according to the hackaday project. And an 8mV/div sensitivity is also pretty abysmal.
I liked the part of the “Haasoscope Pro v29 Updates” video(Released today) where he shifts the data a bit to compensate for sampling inaccuracies, but then, when the oversampled sine is jumping around with around 30 degree phase jitter and he calls it “pretty acceptable” (@11:00) I lost my last bit of interest. His approximation algorithm is completely failing in that case. That can still be improved in software later, but the too simplistic analog frontend can not.
Overall, I would be more interested in a relatively simple scope myself, as long as both the hardware and software is “pretty good”. Something comparable to the Owon VDS1022I (EUR 110, 100Msps, 25MHz bandwidth, 8-bit), but with good Linux support, as a companion to my Siglent SDS1104X-E (Which is quite good, but has a far too loud fan). A few months ago I had a brief look at the picoscopes, but they have made a very weird user interface, and prices go up extremely quickly for anything but their simplest model.
Also had a look at the Labnation Smart scope. (Also Open source Software), but it’s relatively expensive for the hardware, also has a very limited front end, and there does not seem to be much development going on over there for quite a few years now, and that also made me hesitant.
