The spec sheet says it needs 12v. Perhaps a modified upi adapter would work. Does anyone have one of these to test?
Also, the B versions require 5v 3A, so these probes are rather power hungry.
I probed voltages on the upi adapter from my RCP500 and found supply voltages across the top row of pins.

I don't know what ampere it uses in practice, as I havent tested it, but Micsig's official power specs, some of those should be taken with a pinch of salt, at least in the past.
I recall somebody looking for a PSU for their Micsig-tablet-scope's, and was hard-set on matching Micsigs official PSU 12v/5.417A (65watt) https://tinyurl.com/6zkhze47
though these scopes are not anywhere close to using that, it's under 50% of that, around 25W "charging" and around 30W "in use & charging" and the org Micsig PSU was somewhat noisy.  https://tinyurl.com/3v5v6a47
I don't use the incl PSU with my Micsig scope, just use power banks with PD 12v support, and with a TypeC to DC barrel decoy-adapter.
But I do recall that Micsig indicating the "B-variant" for their Micsig-scopes without Micsig's new proprietary prope-interface and gave the impression it could be run from the scopes USB, and the USB-port in all these Micsig-scopes are not able to deliver anywhere around 5V-3A, not even half when I run the secondary display from it and had to dial down the brightness..https://tinyurl.com/24hn9rcw

Has anybody tested the CP503 with the accessory in a normal oscilloscope? (using the right voltage)...

Seems like UPI ones are now discontinued according to the Micsig website.. whats that about?

CP1003 / CP503 (Discontinued)

B versions are still on the market

Micsig seems to end' its "Universal Probe Interface" (UPI)
I reckon they had hoped that other vendors would jump on board on their UPI standard, and later realized it would be a task to operate with two somewhat proprietary probe interfaces for a relatively small international vendor like Micsig.
As they had both their "UPI probe interface" and their "OPI probe interface"
The only scope models, I so far have seen Micsig OPI-sockets on - are their ETO-model & their coming MDO-line. https://www.eevblog.com/forum/testgear/new-micsig-scope-with-knobs-(again)/msg4854149/#msg4854149
