Love your stuff and you usually hit on what I'm interested in, can you you put a little time into the setting up of your scope. Good job as usual.

I have a Rigol 1054z and saw your 1074z and thought . Lol, I looked into it and realized that the 1074z has the function generator built in. Mine doesn't. I WISH I would've spent a little more and bought the 1074z instead. BTW - Thanks for producing videos on how to use op amps. !! Edit: I watched both videos about the T filter, but mistakenly commented on op amps here instead of 2nd video.

[@IMSAIGuy]

Mine does not have any generator.

[@IMSAIGuy]

I'm using an HP33120a generator

[@IMSAIGuy]

The function generator model is DS1074Z-S (note -S)

@@IMSAIGuy Oops. I think the model I googled might not have been yours after all. Sorry for the confusion. That was probably because I didn't review the video to verify the model #. I haven't had my scope (1054z) very long and I saw the word "vector" on yours. That's what got me started. But I comment without doing my homework. I'm still not entirely sure what my scope has and doesn't have. Lol

@@jacobdavis000 no problem. glad you got a scope! I'm sure you'll learn a lot. Scopes are very capable these days. I did a firmware hack on mine and I think your scope might have the same hack. it turns it into 100MHz and turns on all the features

[@pjforde1978]

What do you have crossing each of the four power tracks, and why? Looks like tiny resistors...

[@IMSAIGuy]

0.01uf caps

[@shantk7378]

Have you set the scope to trigger each time the cycle begins? I see a persistence mode to better visualize the virtual line created by the peaks, but I cant figure out the sweep characteristics to recreate this setup. What is the sweep time from 1Hz to 1M?

[@IMSAIGuy]

The HP 33120a has a sync output. I use that to trigger the scope.
