RPL1116 (MSO1000Z) and PLA2216 (MSO5000) Active Logic Probe teardown

oliv3r:
ah, right; ok so I really like the breakout board; what connector are you intended to use? I remember there was talk about HDMI cables earlier which make a lot of sense I suppose, but then your short.

I wonder if it would make sense to 'downgrade' to 4 bit pods then. Seeed studio's boards are super cheap even for 4 layers, and if you have 4 bit pods, you still would get 10-ish pods per order (if you use the full 50 x 50 for a pod. If you'd go with 2.5 x 2.5 per pod (very small though) you could put 4 pods on a pcb and thus you'd get 40-ish pods per order!

Rerouter:
a 8 channel 4 layer pod is only 34x33mm in size, and thats with single layer loading and 0603 components. so you really don't gain anything by going to 4 channel pods.

the breakout board i am currently working on is 65x15mm for reference so far.

there is enough room for 4 pods and 2 breakout boards on a 100x100mm pcb, but that leaves the end user the guillotine them out.

so yep, if you wanted, 20 pcb sets could be had for about $37 posted.

The current ribbon me and dren are working towards are 0.025" or 0.635mm pitch ribbon cable, the same stuff they use on the more professional gear, (very flexible)

oliv3r:
Going to 4 bit pods could not be so much as for size, but price as well of course. And cables. If a HDMI type A connector is used as a cable for example, which has 4 differential pairs if i'm not mistaken. USB-C connector is 24 pins, but unless you put reversing logic in it, I think you effectivily end up with the same amount, 4 differential channels (the other pins would be unused to allow for connector reversal.

If a 4 bit pod would even be smaller (due to the single LM) and cheaper, it's up to members to decide if they want 1 or all 4. Also scale of economics may be achiveable by group-bying the parts 'kickstarter' like or something?
Just a thought is all...

Rerouter:
All i can say oliv3r is, I have posted my current design files only a few posts ago, the software is free (Kicad) and the layout I have used can be cut in half or doubled, the only thing they would need to do it is fiddle with the output connector, and run there own breakout board for whichever esoteric connectors they please.

Noy:
Which connectors/cables do you want to use on the DUT side?
I was thinking about using DSlogic shielded fly wires from my DSLogic but there are some passives used in them.
So i have to buy another set of cables and dismount/mount 0Ohms.

Do you have better ideas?
I think the shielding is good for highspeed signals?
