Hi, could you suggest some reading or resources online that will help understanding the fundamentals then thereafter in depth resources for testing and troubleshooting solutions. Thanks.

When you are going to lunch new course?

Excellent demonstration, thank you. I notice you are using a Rigol SA and not the Siglent SA I’ve seen in previous videos. I’m considering one of them for this type of testing. Any noticeable differences I should be aware of or are they all in all equal?

Hi Sorry for the late reply. I prefer Siglent to Rigol, but it is my personal preference. My Rigol DSA815 is very good though.
