DIY Logic Analyzer Probe and Pods for Siglent (and LeCroy) scopes
oz2cpu:
Here we go, the isolated thread for this project.
More will come shortly.
Thanks to TK and Mike and tautech, for technical help and collaboration.
Any body else are also welcome to come with ideas or comments.
----
The motivation for DIY : original set is at least 400 Euro, and the hardware dont contain anything fancy or expensive.
Some scopes might need a software upgrade or license code to access the logic analyzer features.
I have been playing with a logic analyzer plug in pcb for Siglet scopes.
(NOTE: This type of LA connector will also mate and work with a lot other scope brands too, see bottom of this post)
see the attached pictures, it is 4 layers,
i am also making a 3D printable design to make it click in and hold in,
hold and secure the cables, this way it is super easy to make your own logic analyzer cables,
any type, and any length you like.
I also plan to make a double BNC holder for this pcb,
so the 3D print hold the two extra BNC inputs, so they are nice and stable for two extra 1:1 probes
if any one is interested, PM me.
Scopes this will fit: (please tell me more if you know for sure)

the pcb is on its way
so mean while i work with 3D design of the casing
the lock parts are very small, and hard to 3D print,
I am working with several ideas for this, one is even to drop the locking, since you dont really pull the wires
and the connector got a good hold of the pcb anyways.
oz2cpu:
this is the probe tip from HP
the good TK found this info.
I want to split the 250 ohm into two resistors, like this:
i expect the two 120 ohm needs to match the cable used,
and also trim the value of the 8.2pF for hi speed performance,
see attached
oz2cpu:
The PCB edge connector needs to be sanded to a well defined angle
I searched the net carefully, and found a bit different results,
from 20 to 40 deg.
so here is my idea : a sanding holder in 3D printed plastic, so the edge can be made nice and straight at correct angle,
we want to take good care about the scope connector, so i think 20 deg is better
