So I finally got my Module Tester build up and running and all looked ok as the menu, buttons, encoder etc. were working as expected, but once I started using the in/outs of the module I noticed the signals were pretty wonky. I was first testing with a multi-meter and noticing the clock output was giving me some kind of triangle ramp between 0-5V so I then hooked it up to a oscilloscope and this is what it read.
I then tested all the other channels (gate out, cv out) and they all showed similar readings.
Could this be a power supply issue? I am always super confused with the difference between AC/DC power. I was using an AC adapter (at least I think I was) but it stopped working after about 10 minutes (no clue why) so I switched to one with an input: 100-240V and output: 12V -...
What I see here is a perfectly fine square wave going through an AC-coupling (DC-removal) filter. Not sure what scope or probes you’re using, but there’s an AC-coupling setting or switch wrongly selected somewhere.
I am using my MOTU828 as an oscilloscope so theres a chance it doesn’t work quite like a “real” oscilloscope, but I am unfamiliar with the tool. I’m going to test it out a bit more.
