Best USB Oscilloscope for makers and hobbyists

I’ll be honest right from that start here, this model of Hantek is the one I regularly use in my own setting, and it has been extremely useful from day one.

Its anodized metal casing is completed by two rubberized plastic ends, which allow the metal to stand off your desk and provide some protection. You can pull them off to make the unit smaller, but there’s not really any point as it is only a slimline box to begin with.

At one end you have the BNC connectors to attach your included probes, which also come with some extra bits that can transform then from their regular needle points to clips and hooks – useful for attaching to the legs of chips on a PCB board.

There is also a couple of connectors, one for attaching your ground clip to and a second, which comes in useful for testing at set up, that outputs a 1KHz square wave signal at two volts. This means you can test and demo the unit by directly attaching the probes back onto the unit, and you should instantly see the generated signal on your PCs screen.

Once you have the unit up and running, it’s plain sailing, although actually getting it up and running is more annoying than it perhaps needs to be, To download the latest software involves some negotiation of the manufacturer’s website, in Chinese which isn’t ideal.

Fortunately, as ever, the internet has come to the rescue, and a quick google will reveal some nice non-official firmware and software that will open up more options.

If you are a keen hobbyist like myself, then it’s unlikely that you will need anything more “professional” out of a USB scope. If you did, you would likely be looking at an all in one unit anyway, rather than a USB model. 

It needs a bit of tinkering to get the best results from it, but if you are in the market for this sort of thing in the first place, then a bit of tinkering is what brought you here anyway.

Picoscope is very much the company vying with Hantek for the lead in the USB scope market. Their products tend to be priced a little higher and generally come across as a step up from Hantek’s offerings, but that said, we aren’t looking at professional equipment here, so a nicer, the brushed metal blue case doesn’t really affect things.

Picoscopes are however a great alternative if you are dipping your toe in the market. They aren’t always easy to get in the USA, certainly seemingly more so during the pandemic, but you can always get Amazon to ship you one from the UK.

Be careful as certain models inexplicably do not come with the probes, which will knock about $20 off the price, but if you don’t have probes already, well.

Not all probes are equal however, and you might have a set more suited to your use, so that is a good opportunity to bring the price down in line with the Hantek model above.

Like the Hantek, it has its own built-in waveform generator for testing purposes, and this one features just 10Mhz of bandwidth, making it even more restrictive than Hanteks, but again, for general hobbyist work, it will be just fine.

Taking on the Hantek’s and Picoscopes of the world is Owon, another Chinese manufacturer of oscilloscope equipment, and once again, there isn’t much markedly different from the other two on show here.

One benefit of the Owon is the slightly increased bandwidth of 25Mhz and an ultra-thin case that makes it a sort of a hybrid of the two we have already reviewed as it features plastic end caps like the Hantek.

As with the other two, it comes with its own handy wave generator for testing and a nice software package that gives it similar functionality to the hacked Hantek.
