Note: I haven't attached a schematic because it's not part of the question. I'm trying to solve my circuit's problem on my own. I'm making my problem a learning exercise.
I have an arduino hooked up to my PC. It is at 5v. I have a servo hooked up to a buck convertor powered by a separate laptop power brick. The servo is at 7.2v. In order to ensure that the 5v USB doesn't interfere with the 7.2v servo, I have used a photocoupler/Opto-isolator.
Currently, the circuit is not working correctly. That is to say, the servo does not move. I have verified each output and input using a multimeter. I'm currently of the opinion that I have a signaling problem between the arduino and servo. The servo does, of course, work.
My question is, can I safely connect my oscilloscope, using 2 channels, to both sides of the photocoupler using normal (non-differential) probes?
My oscilloscope does not have isolated inputs. My oscilloscope is an MSO5074.
Thanks!
PS: I'm using a photocoupler instead of a transistor because I wasn't sure how the buck convertor and the PC's PSU would interact. I did not want to take any chances. I will learn more about these kinds of things in the future, of course.
