BSD ( Bit Serial Data line)
The bit-serial data interface is a single-wire data bus with a data transfer rate of 1.2 kBit/s.
The following components are connected across the bit-serial data interface with the DME control unit:
- Alternator (varies according to version)
- Intelligent battery sensor (depending on model series)
- Electric coolant pump (depending on variant)
- Oil condition sensor (depending on variant)
DME is master controller
The first check: ALT, needs to be OEM
see attachments for various known good scope images from various scopes.
The snap on capture is flawed not due to scope speed/resolution, it is not setup up correctly- timebase is incorrect. It has WAY too much time on the screen. This causes the scope to alias or "guess" where it should "connect the dots" on the screen
This is a common issue with SO users. The scope should be setup somewhere a 50 ms time sweep which is the equivalent of 5ms per division.
The buffer would fill and then the capture would be stopped and zoom out and then zoomed in.

If I need to remove the link to the image, I will. The other link is just to their website that is publically viewable by anyone. It's not a private webpage.
I don’t see an issue here Steven, you simply linked to an image on a public webpage which supported embedding.
