In order to simplify the project, and given that I wouldn't need to distinguish what source the noise comes from, I could use only S1 and X sources. And here is my last question. If I don't lock the sources to one another (say two HP 10811), what is the unconvenience? An additional signal in the spectrum, or something else that I don't figure now?
