Yeah. In general i'm just trying to avoid interconnect hell like proprietary active probes have

Ok baby is in bed and i opened the oshpark envelope, i have three probe tip characterization boards
<azonenberg>
Time to have some fun
<azonenberg>
Veeeeery interesting...

<azonenberg> Ok so, first things first: new LeCroy solder in tip resistors and our 100 ohm HMLs are very close. Old LeCroy solder in resistors are slightly off, but not by a lot
<d1b2>
<azonenberg> old in blue, new in red, HML in green
<d1b2>
<azonenberg> second: new fixture gives data i actually have some confidence in. the old one was garbage. old in red, new in blue. Tl;dr the poor return current path on the old fixture ruined the data
