Time for another review of an inexpensive oscilloscope. This time we have the Hantek PSO2020 in an interesting and unique for factor. It's cheap but will it work well enough to allow me to figure out what's wrong with this broken Commodore 64?

The difference of the test harness > Rev. 0 is: The keyboard feedbacks and the control port feedbacks are the same and both go to CIA 1. So actually, you have to test two passes, one with keyboard dongle and one without. The newer revision not only switches the user port feedbacks (like the original), but also the keyboard feedbacks. So you fully test the ports without removing the keyboard dongle. And the switching happens on the user port dongle. That is the reason for the 3rd 4066 on that dongle. The feed trough on the cassette dongle is also quite useful. The feedbacks for the cassette port are also on the user port dongle. So connecting it without the user port dongle, it is completely neutral. It indicates the motor and sense signal. You can also use it to tap the 5V on the cassette port of the PET, because the PET does not provide it on the user port. Also, it works with the VIC-20 test harness. And you can easily probe the cassette signals with the scope.

Just as a reminder for some, USB ports on a desktop pc are not isolated from the mains earth/neutral. Keep that in mind when using the ground clip on that probe, or you could have a very bad day (and so could your pc). I have no idea how that Hantek probe is wired internally, or what type of circuits people would try to use this probe on. Safety first.

The Hantek 6022BE is not isolated from the USB ports, so my gamble is this cheap oscilloscope isn't either. So use an battery powered laptop and/or an isolation transformer for high voltage stuff. It doesn't affect the usefulness of the scope a lot, you just have to be aware about it.

@adriansdigitalbasement Жыл бұрын

It's most definitely not an isolated design -- not on something this cheap. Someone else mentioned the Owon VDS1022I which is a USB scope that does use an isolated design, and looks to be quite a bit better. (Also nearly 2x more expensive)

Not everyone is in a position to drop hundreds of dollars on a tool they may only use a few times a year, and these low-end scopes are fine for that use case.

Might be interesting in a case like this to see the difference in behaviour between this device, your much better logic analyzer, and a simple logic probe when poking around to track this down (of course in this particular case it's already known where to poke so a known failure(s) may be a good example to use)

IMHO, if the Hantek probe had a scope ON THE PROBE itself, I'd be more interested, Otherwise it's an oversized, clunky unit making it MORE likely to short pins while you look at the PC.The other Hantek scope, as you mentioned can set in your field of view and you have a thin probe which will be much less likely to cause problems. Good Luck

@adriansdigitalbasement Жыл бұрын

The width of the probe tip (the last couple centimeters) on this is exactly the same as any oscilloscope probe, so it's not really more likely to short a chip. It's probably not going to be able to get into really narrow spaces.

After your video about the Hantek USB scope I was thinking about purchasing one, however since I'm the kind of person who always has to research everything thoroughly, I stumbled upon a thread on the EEVblog forum and it turned out it was a terrible device and there was a way better, slightly more expensive device made by Owon (Owon VDS1022I). I ended up purchasing it and pairing it with a Raspberry Pi 3B and I must admit, for an occasional tinkerer like myself, it's actually half way decent. There's open source software for it (it's also compatible with the Hantek btw) that's FAR better than the original software. Anyway my point is there are most likely better alternatives for the polished turds that Hantek is making....

@adriansdigitalbasement Жыл бұрын

Perhaps -- it looks like that Owon is $110 from AliExpress -- and while it does look a lot better, it's nearly 2x more expensive. For a person who just needs basic test gear, why bother spending that extra money? You can keep spending incrementally better money ... eventually reaching $400 to get something really good, like the Rigol DS1054Z. It's so easy to fall into the trap of "spending a little bit more" to get something better .... The EEVBlog Forums people are gear nerds -- they aren't generally fixing C64s, so their use case for things are going to be different. The point of the video is to show that you can fix something even with the most basic cheap stuff. I can pretty much guarantee the better and more expensive Owon won't result in a person being more like to be able to fix a C64 over the cheaper (and definitely less good Hantek) My first "good" scope was the Rigol 1054Z which I don't use much these days because it's not great for making videos -- but with it feature unlocked, it's really hard to beat... (I see it's $420 right now, funny I paid less a number of years ago when I got mine.)

Reverse engineering such a device costs a lot of energy. The 6022BE got lucky that some people did want to spend that effort, and any software developers can just find open source firmware, drivers and documentation. That... isn't true for any piece of hardware that Hantek produces. Hantek doesn't publish technical documentation, so any third party software will have to reverse engineer it.

If it had actual screen I could *kinda* get it, but it seems like a gimmick, compared to more "typical" PC scopes. Like, $60 is cheap, but Hantek have 2x20MHz channel box one for like $10-15 more and extra channel is definitely worth that
