Spectrum Analysis: Averaging or Max Holding - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

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.
