Analog TV Equipment: R&S SFM test transmitter and CCVS video generator.

Video Description

This video is a bit different from my previous videos and not related to optics. I made it purely out of interest for older (analog) equipment and technology. The video discusses the principles behind analog TV transmission technology, such as color encoding in composite video signals and RF transmission and modulation methods. For my demo I used a small TV set found in the street, a Rohde and Schwarz SFM test transmitter + CCVS video generator, and a Signalhound USB spectral analyzer.

Please let me know and I will set it straight. Joshua Reich gives a nice detailed hands-on demonstration of composite video in this video: https://www.youtube.com/watch?v=nApAw_-wka8 @Technology Connection Youtube channel has made several excellent videos about analog TV technology. It discusses the subject more detailed and also from a different perspective (USA). https://www.youtube.com/playlist?list=PLv0jwu7G_DFUGEfwEl0uWduXGcRbT7Ran Gavin of the Slomo Guys shows some REAL high-speed footage of a color TV screen How a TV Works in Slow Motion - The Slow Mo Guys https://www.youtube.com/watch?v=3BJU2drrtCM If you want to know more about the entry level Signalhound SA44B spectrum analyzer I used: https://signalhound.com/products/usb-sa44b/ Wikipedia contains pages on almost every specific subject discussed in this video. If you need more info then just search for the subject in Wikipedia. However, unfortunately most of the articles dive deep into the matter, which can be quite frustrating if you are not an expert. -----
