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

<< < (22/50) > >>

Muza:
A quick'n'dirty render of what I meant. Last number is of course 15, not 16...
Essentially, it does not matter if we decide to use any interim connectors between the scope and the pod, in any case I was planning to 3D print a case and then make a silicone mold of out of it.
Afterwards, casing can be poured in PUR or Polyester molding the idc connector with pcb or idc connector with the flat ribbon cable.

Like this  https://www.mouser.com/ProductDetail/3M-Electronic-Solutions-Division/9150-4500PL?qs=sGAEpiMZZMs%252bGHln7q6pmzuniGC9vGvgdUx8jl58Y%252bI%3d

I am sure they are found cheaper on ebay

Muza:
That's the 3M 9150-4500 Series i used the CAD from

dren.dk:
I did look into USB-C, it does have 4 pairs, but it's not keyed and supporting rotation of the connector would be somewhat hard to support the reversible connector.

USB-C also has built in chips that make it harder to abuse for something like this.

Natually it's possible to use the 4 pairs for the data and then implement a proper +5V power supply that generates the +4V, +2V5 and -2V5 rails and to feed the vref through one of the connections, but it's also somewhat hard and not all that elegant.

I think someone who wanted to (ab)use a consumer cable for a 4 channel pod would be best served with HDMI, though pure mini and micro variants don't seem to be very common...

Muza:
That's a valid point regarding the polarity with USB-C... which with correct layout would just mean that two channels would be swapped if inserted "upside-down". Not an ideal case.

Going back to the 50-wire flat ribbon cable: maybe can just stack two narrower ribbons on top of each other to make the connection between the scope and the pod less bulky just like the Rigol RPL2316
