Hello!
I was unsure whether this question would be more fit for "Beginners" or "Test Equipment", but because I am specifically talking about the SDS1104X-E I figured it should go here.
This is my first oscilloscope, I have already read the manual, but I only saw one mention of current when it comes to measurements and that was in the "Unit" section. I can only change the channel label from V to A, nothing else like scaling is mentioned. My question is just, am I missing something? The value that would be displayed would only be immediately correct with a sensing resistor of 1\$\Omega\$, and having the correct value on screen aside, I would have to pick very specific values like 1, 10, 50, 100, 500, etc. In order to be able to immediately make sense of the value on screen.
My thought is that since the oscilloscope has a math function where I can divide one channel by another, or a reference waveform, surely I should be able to just divide a whole channel by a fixed value, that seems to be an easier and less complex (computationally) task, but I also could not find anything in the scope that would allow me to do such a thing. I guess technically, I could run a DC waveform in one of the channels from my power supply, setting it to some significant figure of the value of my sensing resistor, so that afterwords I can divide the by it, and then further in my head the magnitude, but this is just a hack and I wouldn't really consider it practical?
Are there any features that would help with quick current measurement that might be paywalled (that I could maybe unlock)?
