Thank you for this video. Whenever I have a question about something in my little hobby home lab, I can rest assured that you're going to have the answer for me. Cheers!
To make use of the display functions and the adjustable resolution bandwidth how about separating a constant signal from the noise in the case of a satellite LNA. It has a crystal stabilized oscillator and a binary divider. That binary divider delivers a rather low power but very characteristic spectrum to the output with many lines of different intensity which is interesting to observe and to analyze going deeper and deeper into it.
@@galileo_rs imagine an oscilloscope with 1 million point depth, very common. the display is a subset of the data and you can zoom and move around. so the spectrum analyzer may have many more samples in memory also. I think it is more common that the data output is exactly the same as the display resolution.
@@IMSAIGuy I understand what you mean, I'm concerned that others won't. Using accurate terminology is important to avoid confusing people that are still learning about this. But hey, you made a video about it and that is good and more than most of us have done.

Thank you for the class room.
thanks, i was indeed thinking what the different modes do
No mention of the averaging it does over time which is apparent with the jump in noise whenever you change modes.

Tank you, very interesting and helpful explanation. But you could use the trace functions to show the different detect modes overlayed on one screen.
Normal looks like the noise floor in my old HP SA. I think normal best represents inherent uncertainty.
Merci. Interesting.
According to this, if I export the raw data from the SA I will get 1024 "pixels"?
no, the data will be a string of data, sample points, the number of points may or may not be the number of display pixels
@@IMSAIGuy Can it be greater than the number of pixels?
@@galileo_rs yes, depends on the system
@@IMSAIGuy So if it is not dependent of the resolution of the screen what does it depend on?

Pixels? It seems you are discussing sampling rates. Pixels are image resolution (not sample resolution) and that is just going to confuse people.
Each value on the screen divided by pixel count contains many samples that are used to get a peak or ave for each point
