REL #17 Vector and IQ constellation diagrams on an oscilloscope

Описание к видео REL #17 Vector and IQ constellation diagrams on an oscilloscope

In this video, I investigate vector and IQ constellation diagrams on an oscilloscope, using an R&S SMIQ as the signal source.

03:04 Background and theory
17:51 IQ signals in the time domain
26:00 Parallel bus decode of IQ data streams
28:05 Vector diagrams
32:10 Using trace intensity (‘rainbow’) in vector diagrams
34:48 Constellation diagrams
42:02 Observing imperfect IQ signals
47:33 Final thoughts

Information on how to use the (undocumented) XY mode blanking function in the R&S RTB2000 oscilloscope can be found here: https://github.com/RudisElectronicsLa...
