Why not use standard lab scopes? was created by RimmersTechSWE
Is there a reason why we dont use standard labs scopes in auto repair? I mean scopes like Rigoll, UNI-T Keysight etc some of them seem to be half the price of a similar picoscope while being much higher speced and without the concern for USB connectivity problems. Very interested to get some input on this before I go out and buy a scope.

Bench scopes with the main exception of some of the Owon models are hampered by the need for mains power supply. Even on the Owon SDS with the optional battery pack especially the faster models the length of time working on battery power is limited --- considerably shorter than the manufacturers claims.

Take a look at the Ditex range of automotive scopes they do PC connected scopes and pad style scopes at a price much lower than Pico's automotive scopes the software has automotive pre-sets and connection guides and example wave forms. They also have very good on Knowledge Base Library on the website.
They have agents in most countries and also sell via eBay shop (search eBay on carscope_ditex)

Auto Ditex Website link

On the otherhand if you want a simple starter level PC USB general purpose scope at a bargain price checkout the Owon 11022i --- it is a lot better than the Hantek 1008 but will need input attenuators for checking coils and injectors

Thank you for your reply. I have seen Diagnose Dan use the ditex pad scope and it seems pretty appealing but still if it's just the power cable that ias the obstacle to using a bench scope that's not more of an obstacle than the italian restaurant of usb wires that comes with a USB scope. Considering that the bench scope has better specs for other things that I might use it for. I thought it might be a ruggedity problem that might be the reason.

Thank you again for your time. :)

That is just a re-branded Hantek :-(

Ok so that means it will work then? Even thought it might not have automotive presets. What makes it not as good as the other one tohugh? The software?

To be exact that scope is a Hantek 6104PC which generally sells for about £170 or 200 Euro The software it is packaged with is the older style of software withe onscreen knobs

You will find very many comments accross the internet and in this forum on Hantek scopes, the serious experts reviwing them say the sampling rates they quote are way over claimed, the software is horrible to use and build quality generally inconsistant and poor.

Probably the cheapest useful scope Owon VDS1002i (note the i suffix) --- PC software is really nice to use, surprisingly performance at 25mhz per channel isn't over claimed by the manufacturer. A lot of Chinese scope manufacturers might claim say 100mhz but in reality that is closer to say 50mhz and the processing hardware is shared between channels so the more channels you run the slower the performance of the scope.

I agree Hantek is Junk. Hantek.com has been down for a week now. The support is horrid. The software is insane. The amount of storage they can do is insufficient for many things. I have been stuck with one for a while. I need a Pico like a Hobo needs a blanket. You can get a 2 channel non auto pico and do many of the same tests if you get it setup right, which is something I am considering, but I think I would be better to just save up and get a 4 channel pico. The other thing is the amount of Known goods there are in Pico format these days.

Thanks. I will probably buy a pico or ditex when I have an income from it. Right now I have no real income at all and am just looking to practise using the scope for different things. (I repair hifi equipment aswell). That's the reason I thought I might get a bench scope.

Hi Andy,
I love the Owon as well and will keep backing you up on that.
The settings kind of reminds me of the Sun LS 2000 that I had but died.

If you're looking for a cheap and relatively good quality scope(way better than hantek) check out the Loto OSC482. It comes with software for a pc or laptop or you can plug it into your android phone or android tablet using the HScope app. I added it to my Launch X431 which is just a Lenovo 8 inch tablet at heart. Absolutely awesome and I made a YouTube video on it
