Engineer's Log of Mark W. Persons |
 |
December 5, 2008:
After many months of research and deliberation, a new Agilent N9340B
Spectrum Analyzer was ordered and delivered to M. W. Persons. This
is an excellent tool to supplement the existing IFR A-7550 Spectrum
Analyzer, which will continue to remain in service for some projects.
The new analyzer will do all of the necessary measurements for HD Radio
where digital carriers are added to existing analog carriers on AM and
FM stations. Mark is a happy guy! |
 |
Here is an example of a measurement made on an AM station to prove compliance with FCC rules. |
 |
Here is
a measurement made on an FM station running HD
IBOC (In-Band On-Channel)
mode where digital modulation added to the existing analog modulation of
the station.
|
The stories go on and on. Stop in
again sometime. I'll leave the soldering iron on for you.
