Spectrum Analysis: Averaging or Max Holding - RF Cafe Forums

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.
