Oscilloscope Confusion
Posted: Fri Aug 24, 2018 1:07 am
So, I am having a bit of a time with understanding Oscilloscopes. For digital, I just ignore most of the information and look for a simple signal. But Analog has tossed me for a loop here.
For instance, I think the yellow indicator for my probe 1 should be at 0 volts. Yet obviously it doesn't work that way. I have even seen when I connect to a circuit, the signal kind of travel up as if the scope is trying to fit it on my screen. I don't need it to do that, I would just adjust it myself if I wanted that.
I don't do anything special with my scope at all. Just want to connect it and adjust the freq and position of the probe.
When I was looking at the Video signal from Mutr recordings, I know where 0 voltage should be. It should be at the sync pulse part. but on the scope, it looks like halfway through the signal is zero volts. Not even possible!
To me where I have the arrow should be 0 volts and it should be at the marker that says 1. But no, it is way down below the marker making most of the signal below 0 volts. Not possible.
I really like my scope, I just don't understand. Maybe I need some online course to understand what it is dong. I almost bet if I pulled out my old 4 channel scope this would not happen.
My Scope is Siglent SDS1052DL+ Please don't go look up that scope to answer. Just looking if anyone has an idea.
Any suggestions would be appreciated.
