@Paul Denisowski, thank you so much! But what is the purpose of the power measurement here in wireless communication?

For one, wireless communication power must conform to regulatory limits.

For channel power measurement with Integrated Bandwidth method, would the RBW setting impact the resulting channel power?

That's a great question. Generally speaking, you should use a RBW that is a couple of orders of magnitude smaller than the channel width. For example, for a 20 MHz wide LTE channel you would want a RBW around 100 kHz and for a 5 MHz wide WCDMA channel a RBW of about 30 kHz would be appropriate. Using a narrower RBW (slightly) increases measurement time but improves accuracy, especially if the power is not uniform (flat) across the channel. A narrower RBW will also minimize inaccuracy at the edges of the channel caused by the shape of the RBW filter. A spectrum analyzer with a channel power measurement function (like all R&S spec ans) should automatically choose an appropriate RBW based on the channel width, so in most cases you shouldn't need to worry about manually selecting a RBW. Thanks again for the great question!

It's coming! But I probably won't be back on spec an topics for a few months :)

Hello, thank you for the video. How do I calculate Integrated Bandwith (IBW) power by getting the trace from the Spectrum Analyzer? Let's say I have a 20MHz BW carrier setup at 1GHz. I get the x and y axis trace from the instrument, how do I calculate the IBW power from that imported trace using for e.g MATLAB or Python?

Most spectrum analyzers preform this as a built-in function. Check your manual.

During measure channel power using Integrated Bandwidth, shall I use trace Average or Max Hold for better calculation?

The general rule of thumb is to use an RMS detector any time that you are measuring power with a spectrum analyzer. There's no reason you can't use average, max or min hold, etc. but RMS is what I would recommend. This would apply if you were measuring power in zero span mode as well.
