Passive probes and quality

@IC_Toaster
Having myself "collected" some probes over time, I can tell the following,
I have:
p2060 probe (chinese version of some sort),
p4100 probes (no clue how I got these ever, but I have them next to me) (2x) of different brandings, both chinese versions.
Uni-T UT-P03 probes (2x) (also chinese ofcourse)
And I can honoustly say that build quality wise the UNI-T probes look way better then the Chinese p-series probes.
Ofcourse it's all about the interals, but usually the exterior tells something too and thats all I can objectively say without actual testing (something I can't do, sorry)
Anyway:
- Plastic looks the same, but has a different little less plasticy feel
- Cable are a little softer
- Plastic cover over the BNC connector is nicer, sturdier. Rotates smoothly.
I looked online, but couldn't find any reviews, comments or anything on these probes, not good once / not bad once.
Generally I have an oke view on Uni-T product. Don't know about the scopes though.
so if looks say anything, it could be that there is a small hidden gem somewhere in these, who knows.
Kind greats
Matthieu

Strangely I see various ProbeMaster multimeter test leads at Welectron, but no oscilloscope probes. Makes you wonder how they set up and split their distribution channels?
Personally I went with Testec as well since they are easily available here, and have been happy with the probes over several years now. Only complaint is that they don't include ground springs with the midrange probes. (But they do include BNC adapters.)

That is weird. I thought they previously had scope probes too. Maybe out of stock? I dunno, might be worth emailing them to ask if anybody needs probes from them.

I see it is possible to get 2 P2200 probes under 19€.
Probably Testec is better, but quite more expensive.

I looked at the P2060 probe, compared it to the P2200 and the specifications differ only in two places. Rise time and compensation range. Now, I'm actually wondering if the P2060 would easily go to 200MHz or not. There is nothing really in these probes that would limit the bandwidth (other than 0.1 cent capacitors), and I think it's entirely possible they have the same internals.
I think you should test your existing probes, if the frequency is your only consideration. A RPi Pico will make a rise time of about 2.2ns, which is 160MHz, very cheap way of testing this.

Aldo, THANK YOU. I was able to deduce the link to the course tutorials, labs and text. I do use MIT open courseware, but it would be great if we had a list of open online course material in the beginner section.
