If there are automotive techs reading this now, don't hesitate, buy this now! It has AC coupling, so you can test all sensors that are AC signal generators (wheel speed sensors, certain cam/crank sensors, alternator ripple, etc.) In DC coupling it works well to check computer output driver circuits, Hall effect sensors an d checking output frequency and PWM outputs. I say this excitedly, probably only as an automotive technician. I just have to say, wow! For $165, you cannot go wrong. I finally had the money to jump on this scope, not really knowing what to expect based on other reviews, mostly related to software issues. I have used many automotive specific versions of oscilloscopes as well as having owned a few myself. We're talking about a 60Hz signal here.I am an automotive technician and have used oscilloscopes for diagnostics and troubleshooting for quite some time. But even a 10Mhz Analog CRT scope will likely do everything you need. If you are willing to spend the extra money, the Rigol scopes are a great option for that sort of thing. At the very least, use an old computer you can stand to lose. All it takes is for one of those cheap parts to fail and you have HV AC going into your USB port. Where the OP is asking about AC mains, I'd strongly recommend against a USB device. With the smaller market, it probably doesn't make sense for a big manufacturer to do it though. I doubt most hobby level users need more than 10Mhz most of the time. Perhaps lower bandwidth/sample rate, it's not like most of us need to scope 100Mhz signals. It would be nice if someone made a hobby level scope with good quality. It doesn't help that the specs often lie about very basic easy to test items and most seem poorly designed. I thought about the USB based devices, but regardless of the specs, the reviews tend to be very mixed. They get great reviews and are much more portable than my old CRT scope. If my analog scope ever dies, I might spring for a Rigol though. I normally use it if I want portability, and use an EBay analog CRT scope for the bench stuff as it's faster to dial into what I want and I rarely need to store the traces. I have a DSO quad I use a fair bit and it works fine. It's a limited tool, but if your needs fall within it's limitations, it gets the job done. you can get a new one for about 60 bucks.įor low frequency stuff, or if you want portability, the DSO nano isn't bad. I've seen used conventional oscilloscopes on Kijiji and CL for 5 times this amount with the same specs.Īnd i'm happy with it. It's dual channel, has storage capabilities and able to interface to PC software for data capture and analysis. Compared to the Nano's 1MHz bandwidth (1 MSa/S), this would be a better shop tool. This seems like a really good product for very little money considering the specifications. It is sold by Deal Extreme out of Hong Kong for $70 including free worldwide tracked shipping. I was looking at various retailer's web sites today, looking for Arduino components, when I came across Hantek PC Based USB Digital Storage Oscilloscope 6022BE with 20Mhz Bandwidth (48 MSa/S) . The Rigol scopes (DS1052 etc) are perfectly 'decent' and more than adequate for most purposes, so dont be put off by high prices.įor measuring high voltage stuff, the very last thing I would do is connect a high voltage source to a USB scope that is connected to my PC, too much can go wrong. I would not consider a USB scope again.įar better to have a standalone scope that stands a decent chance of having a low noise supply, and is isolated to boot. I bought a Hantek DSO 2090 Complete load of junk, there is far to much noise on the signal input to make it feasible to use for any signals below 1V.
