Hi, just ordered a DSO203, to work on solid state pinball machines. The processor technology is limited to 80’s Motorola 6800 series, running at or below 2MHZ.
I’m hoping the bandwidth of the scope is enough to be useful for this technology.
I couldn’t find anything stating the actual speed of the digital inputs, and I’m not even sure if the scope comes with digital leads.
Mostly, I just need to see activity on lines, and to be able to tell a high from a low, and observe any noise that might be on the power lines, etc.
Voltages used in a pinball machine of that era, are +5 +12 +28 -100 +100. I’m hoping that the probes in 10x mode will be able to handle +/- 400v. Is this assumption correct?
Can the digital inputs be used for triggering the scope? Are the digital inputs compatible with TTL level signals. I read that 3.3v was max, but I’m hoping that they’d be ok on 5v also.
