My scope was delivered on Monday. It's sure nice. Now what? ;-)
Actually, a couple more directed questions...
I watched the EEVBlog about not blowing up your scope (https://www.youtube.com/watch?v=xaELqAo4kkQ). And I admit it has me a little spooked (perfect time of year for that I suppose). Next I was reading the manual (http://beyondmeasure.rigoltech.com/acton/attachment/1579/f-0506/1/-/-/-/-/MSO1000Z%26DS1000Z_QuickGuide.pdf) where it says that the scope operates in Measurement Category 1. The definition of which is:
Measurement Category Definitions Measurement category I is for measurements performed on circuits not directly connected to MAINS. Examples are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS derived circuits. In the latter case, transient stresses are variable; for that reason, the transient withstand capability of the equipment is made known to the user.
Question 1: I am okay to use the scope on circuits powered by my bench PS's, right? Ultimately they do connect to MAINS (as I understand MAINS)...
My project involves using PWM to control an L293D circuit, pretty straight-forward stuff. Output on the L293D is roughly 0 - 15v. I have been searching around the forums and the Internet in general and it seems possible to inspect the various timers and my software configuration of said timers with the scope.
Question 2: I should be able to observe the overflow registers on the AVR as well as the output voltage on the 293 to correlate the PWM signal and the output voltage; but should I worry about blowing up the scope?
The manual says the scope can take up to 300Vrms on the leads. I am still just super paranoid as it took months to save up for the scope.
Note: This is as much for experience with the scope as it is for troubleshooting my circuit.
Thanks for any and all feedback!
