What Is RF?

Really good video, I loved the opening of you moving into frame with the title also

Hi, It was a little experiment, and I wondered if it may look a bit silly, but it seems to have worked. My studio is a bit small so I have space restrictions. I am really pleased that you liked the video and took the time and trouble to leave comments. All comments, positive or "constructive" are always welcome. Very best regards and I hope you have a Happy New year - from Harry - SM0VPO

Hello Jexx7373 The next video will be "RF Safety", but I intend to have a bit of fun, shooting down myths and tinfoil hats, as well as being serious. It will be a bit funny, but it will cover everything in the radio spectrum. The storyboard is already written, I need to record it, then spend a couple of weeks clipping: that is the bit that takes the time. Thank you once more for your comment. All comments are greatly appreciated. Very best regards and I hope you have a Happy New year - from Harry - SM0VPO

If it's $2000 for a hobby grade spectrum analyzer then what grade are the ~$200 Tiny SAs listed on Amazon ? :) Thought those were the hobby grade and the 2K ones were the lab grade instruments..

Hi, I suppose a lot depends on the minimum you expect from an analyzer. The analyzers I used professionally were in the region of $40,000 to $100,000, but they worked up to the 50GHz regions, and could decode 5G Cell-ID, SSB, and get stable level data. As soon as you talk about constellation diagrams and >10GHz the prices seems to rocket. For my own lab I chose the Siglent SSA3021A analyzer with a range limited to 9kHz to 2.1GHz, and has no signal analysis, other than the basic SA features. It also has a good clean tracking generator that I use regularly for filter design and testing. Yes, for $200 you can get a simple and effective instrument. I have a Raspberry-Pi with a colour display and an SDR dongle. It makes a great OTA monitor and QRM-hunter, but it is somewhat limited on the workbench. Measuring down to -120dBm is a lot to ask, but the Siglent can do it. Anyway, thank you very much for taking the time and trouble to respond. I really appreciate your comments. Sorry if I was a bit verbose with my answer. Very best regards and I hope youhave a Happy New year - from Harry - SM0VPO
