Well looky here, 16ch MSO probes from both LeCroy and Tek appear very similar:
LeCroy Number T3DSO2000-LS
Tek P6616 and some similar pt#'s
RIGOL RPL2316
I wonder who makes them ?
Find some cheap busted ones from eBay and dissect/RE them ?
Have a look at the current probes….
Siglent, Rigol, R&S, Lecroy, Keysight and partially Tek....It´s all the same...
I got mine today before i got the scope.. lol
Anyway its kinda like i thought, they are a specific impedance set by 100K / 18pF components and the wiring. Your paying for controlled impedance
Now how many need that? all depends on what you are doing, if someone doesnt need it then anyone could rig something up using pci-e header for a few bucks
I debated it but my own laziness wins when its already in hand, i'd say most wouldnt need it unless you already know about controlling pcb material impedance and that's how far you are going and signal tuning / timing.. if not odds are you dont
I have only maybe two applications that fit that out of dozens of others where its not a critical parameter
Edit: another fun tidbit... you can track carrier flights on flightaware.. how cool is that.. watching my scope fly across the pond in real time
