USB was never designed to provide time-accurate sampling to an endpoint, so all kinds of compromises have to be made.
I'm not sure how this matters, as USB is used as a transport to get the data from the hardware part of the 'scope to the display (which is the computer). All of the triggering and time-sensitive stuff is in the hardware.-a
I must admit that I only have two probes at the moment and therefore one for the function generator and one for the scope if that could be the issue?Best regards/John
Got my scope yesterday… an analog GwInstek GOS-630FC and I've been riffling with it since.I just wonder if someone could guide me in a direction to find a good source to learn how to measure gain in a circuit? I have tried the scope with a function generator to add a signal at the input and read the signal at the output but I must do something wrong since the signal is weaker at the output???I must admit that I only have two probes at the moment and therefore one for the function generator and one for the scope if that could be the issue?
Hello WhoopsI bought a new...an analog GwInstek GOS-630FCIt is a 3MHz and time is down to 0,2µS/DIV, and voltage down to 1mV/DIV.As being a beginner with scopes I am still learning a lot but this one seems just fine for my analog testing. It is easy to use, but this scope doesn't have automatic reading of voltages and such so you have to consider probe attenuation and do the math on your own. But that tends to teach me more and perhaps later on I will get a digital scope with more features but that will be when my wallet contains more gold Thanks for the advise.Best regards/John
