This takes me back. Prof A. Budak spent significant time on Butterworth and Chebychev filters in his book "Passive and Active Network Analysis and Synthesis." Nice to see all that theory so beautifully realized.
One thing that a brilliant business man (with tech knowledge) told me that really really stuck in my mind was that you NEED to ASK for things or you will never get what you really WANT. You have to make your desires known, or you will never magically receive them. Be clear. Thanks to your extensive video series about RF, I'm pretty sure that all of the "Tiny" network analyzers of the world are about to get a software update which is exactly what you LOG-ed for ! Thanks for all that you-all do in this RF space.
I really enjoy most of videos,. I often pick up a lot of very useful knowledge, and I appreciate you taking the time to share your knowledge with us. In this video, it might have been helpful to briefly explain why some data is expressed and displayed on a log scale and other data is expressed and displayed on a liner scale. If you discussed log/linear presentation in earlier videos I apologize in advance. 🙂
Nice! Another feature that might be nice -- if you could have the display color the plot to show when the readings were approaching the limits of the instrument -- if the noise is as you say caused by these limits, color the trace red to show that the readings are less faithful to reality.
I think it's the same LPF you built years ago. I made a comment on the mix of the torroid core. The ones you have used are #26 iron powder cores; they must have been #6 material. Red #2 is used for high Q inductors below 10 MHz and mix #6 is used for making high Q inductors for frequencies 14 MHz and above. De VU2RZA
Watching this video was 5 minutes well spent. Thanks
Glad it was helpful!

I’m envious of your new toy.

my video ruclips.net/video/0evhFN-VES0/видео.html gives some insight as to why you see logarithms in some electronic equations
@@IMSAIGuy Thank you for taking the time to answer my question and providing the link.
Hi, thanks for another lesson in getting to know the spectrum analyzer 👍
Nice day 🙂 Tom

Love your IMSAI

Butterworth must have been a brilliant fellow,....
And Chevy Chases grandfather Chevy Chev. I think I got that right 🤣
Imagine what a total hassle the calculation part of the math was back then for all of the famous filter-named-after-them was !!!
Wish my Rigol DSA-815 could do that Thanks Keith
my rigol has log and lin
my rigol has log and lin,,,,looked at my tiny sa ultra,,its not,,would that be in firmware update ? some day
I live IMSAI as well
Would voltage control be possible
: )
Νice presentation tks
