--- Quote from: seppeltronics on March 25, 2024, 02:49:07 pm ---Hello,
for the MSO500/PLA2216:
1) Are the schematics and layouts which are a 100% Clone ?
2) Is the circuitry in the genuine big connector and the pod's ?
3) Is there a good clone that is commercially available ?
Thanks a lot.
Best Regards, Seppeltronics.

to answer your PM as well here...
the original circuit and IC teardown and reverse engineering for RPL1116 was made by Vtech...

the pin connector for PLA2216 (please note PLA 2216 and RPL1116 have different pin out into the scope) was described by TopLoser (and maybe others)...

there is no voltage regulator in the pod, you can see from photos here.. Q3: lets hope there will be soon. currently there are few cheap clones based on some driver/logic IC for less than $100, perhaps similar to this...

you can follow those useful threads or maybe this thread in case if you want to build your own. cheers.

Hello,
the issue that I have is that these EEVBlog-Forum-Projects contain hundreds of posts and if you do not read them all you might miss information. So I wonder if these are in a git-repo somewhere? Got it: https://gitlab.com/riglol/lapod
I did the calculation, about 60..120€ for the comparators(),... + enclosures, PCB's,... if that is no production-run that is commercially available, it's really hard to do it for less than the original probes?
Best Regards, Seppeltronics

Hello,
does an adapter already exist to connect an old RPL1116 active logic probe to a new DHO900 scope?

with teardown photos and rev.eng schematics in this thread and others, it should be easy to diy one. ymmv.

my hope was to buy a ready to use one with the right connectors on.
any idea what connector type fits to the RPL1116's flat cable connector?
in the meantime old links to products at aliexpress/amazon/ebay, that could show these connectors, are dead in this or similar threads.
