I have a device that I need to reverse-engineer. This device has a large multi-conductor cable -- over 20 wires that are jacketed into two circular bundles. I'll need to look at all these signals with an oscilloscope. (Note that I have no need to disconnect and reconnect individual wires, I just need to look at those signals.)
I know of a couple of not-so-easy ways to do this. I could strip off a bit of insulation on all 20 wires (and hope I don't short those bare parts together when I'm shuffling the wires around). Or I could completely sever the cable, get some perf-board, and assemble a short perf-board intersection that takes all 20 wires, puts a jumper in series, and then resumes the cable run.
Is there any easier way to do this? Are there any off-the-shelf items out there to make it easier to probe a whole bunch of wires without issues? Or is there any easier way to do this by hand...?
