Excellent video. You have no idea how even professionals quite often don't know about this. 😢 Btw, I think it would be possible to "pre-compensate" the signal for 1x measurements to get a higher bandwidth.
Well I did see some high end probes that have an on board memory IC and I guess that any compensation related info is stored there. Of course the price tag is a bit restrictive but in a large company, that should not always be a problem... I do plan on making a video on X1 - X2 passive DIY probes, just have to do a bit more research before. I'm happy you enjoyed the video! Thanks!
@@FesZElectronics Another idea is just to make an active probe. At these speeds board design is only really a thing though. Some kind of hybrid approach maybe.
Thanks for the excellent explanation using LTSpice simulation. I would like to know how to probe a high frequency square wave signal like >50MHz (but within the bandwidth of the probe) with relatively long coaxial cable probe. Now the cable becomes a transmission line. I am wondering what happens to signal reflections. Wish you can do a video on how you would tackle this condition.
The oscilloscope does not care about the BW of the probe - you can use any probe BW with any oscilloscope BW; but the measurement will be limited by the piece with the smallest BW - either a 50MHz probe and 150MHz osc or 150MHz probe and 50MHz osc will provide results that have 50MHz BW limitation.
Love you man....no one in the world could explain it better than this!
High quality content as usual
Your videos are great! Please keep make videos. You explain complex subjects in a simple way!
Very well explained

hi can I use 150 MHz probe on 50MHz oscilloscope?

@@FesZElectronics thank you.
