In order to analyse that signal, you can mix it down to baseband, and sample it at 200 MHz, instead of sampling the whole spectrum from 0 to 1 GHz (at 30 GHz). So practical spectrum analysers should be following the first approach. That approach uses the critical parameter of analysis bandwidth which determines the sampling frequency. Look at your device documents about its analysis bandwidth to determine that. | |

| Jan 19, 2021 at 12:11 | comment | added | Ahmet Serdar | I think question is so clear isn't it? there is not any thing in question about document. Also the answer is so basic, yes or no. that is all. I know how works SA but i want to know how to analyze spectrum. but you say "read hundreds documents".thank you sir. | |
| Jan 19, 2021 at 11:13 | comment | added | Marcus Müller | Ahmet, I'm confused. You say you've read about spectrum analyzers, you even mention IF, but you can't piece this together. Could you point us at some resource you've read, so that we might base an answer on that? | |
