This is just incredible, very well explained and clear, thank you.

[@pauldenisowski]

Thank you!

Very Clean explanation!

[@mariofilippi3539]

A very good explanation and clears up the mystery of this mysterious mode. Thanks.

[@pauldenisowski]

Thank you!

Since someone asked: the presentation "Understanding Oscilloscopes - Lissajous Patterns" will be uploaded to the R&S CZcams channel sometime next week. Happy 4th of July!

Creative video, thank you :)

[@jb3757]

nicely done as expected

[@pauldenisowski]

Thanks!

If channel signals can be modified (via math functions usually available on oscilloscopes in scope mode) and plotted in the xy mode (e.g., divide one channel by the other), much more interesting applications can arise. Sadly, in the xy mode only raw signals can be plotted, although it should be VERY simple to implement such capability.

[@pauldenisowski]

Yes, that would be very cool - thanks for the idea!

Finally! The proper way to pronounce Lissajous :) I would always butcher its pronunciation.

[@pauldenisowski]

(laughs) I had to keep reminding myself to pronounce it the "proper way" when I was doing the recording. I'm working on an entire presentation on Lissajous patterns (should be done in a week or two), so you'll get to hear my pronunciation again in that video :) Thanks for the feedback!

Sometimes this can be fun when different dialects in a language pronounce the same word differently. Making multiple pronunciations ‘correct’. In reality as long as the person hearing understands what the person talking is saying then the pronunciation is ‘correct’. Though it’s always polite to get names said they way the person would say it.

[@pauldenisowski]

@@ZaphodHarkonnen This comes up more often than you might think, both for names and for acronyms. For example, both I and most of my co-workers pronounce VSWR as "viz-wahr" but there are also quite a few people who spell it out (V-S-W-R). I sometimes even do an informal poll to see how people pronounce a name, e.g. the "Friis" equation or "Fresnel" zones. As someone who has a somewhat uncommon last name, I'm relatively immune to having people mispronounce it, but I do try to respect how I pronounce other peoples' names :)

Usually you would say Y vs X, since you say position (y) vs time (x) in physics.
Also, great presentation :)

[@pauldenisowski]

Thanks!

But in O-scope parlance it's always "X-Y mode". I think physicists would understand electronic techs (and other users) and vice-versa, though.
