Thanks for your information.

There are not many books about SA, except by Engelson Morris and another one by 
Mr. White.  The "Modern" does have a good chapter about filter bandwidth for 
different kinds of signal.

KC,
I suppose you have read CR Paul's section on this topic.  I had a quick
filp through and the two books that you mention in the materials is indeed
aged.  I recomend that you read Tim Williams's and Tihanyi's section on
this topic of detectors.

1.    EMC for systems and installations / Tim Williams & Keith Armstrong.
            Oxford : Newnes, 2000.
2.    EMC for product designers / Tim Williams.
            3rd ed.
            Oxford : Newnes, 2001
3.    Electromagnetic compatibility in power electronics / Laszlo Tihanyi.
            New York : IEEE Press, c1995.
4.    Introduction to electromagnetic compatibility / Clayton R. Paul.
            New York : Wiley, c1992.
            Series: Wiley series in microwave and optical engineering

To all forum readers,
This got me interested and I am looking for a very old conference paper on
this subject.  Can anyone on this forum help?

Nano,E. "Correction Factors for Quasi-Peak Measurements with Spectrum
Analyzer." 1975 International EMC Conference Record, Montreaux, pp.
156-161.

sincerely,
Tim Foo

Actually I am looking for something about the VBW setting and how it
affects the measurement.  I got feedback from the group that the setting of
the Spectrum Analyzer (SA) shall be at linear mode instead of logarithmic
mode, I understand the explanation from the group, but I do find at least
on EMC standard (CISPR 11), it does require to use logarithmic mode for
average measurement by setting VBW at 10 Hz.  It got confusion on that.

Besides, I want to know more about the detectors, how it affects the
measurement and the details of the construction.  I was able to get one
from the local University for the first one (Modern...), there is nothing
about the detectors.

KC,
I suppose you meant the other newer book:
Modern spectrum analyzer theory and applications / Morris Engelson.
       Dedham, Mass. : Artech House, c1984.
My library have both copies, I can pop around the corner to take a look at
it.  What kind of comments are you  specifically looking for?

Hi all

I would like to seek comment about these two books.

Modern Spectrum Analyzer Theory and Applications / Morris E.
Modern Spectrum Analyzer Measurements

I encountered these two titles from Internet when I looked for spectrum
analyzer related materials.

Best Regards
KC Chan
