Greetings all,

I have a question regarding parametric spectrum analysis.

When we measure parameters like 90% occupied Bandwidth, system noise floor, random spurious signals and phase noise, should we use video averaging or max hold on the spectrum analyzer? How about other linearity parameters like harmonics and IP3?

What are the criteria and conditions we must consider when choosing averaging or max holding?

Thanks.

Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
