Spectrum Analyzers Step by Step (029c)

How do I use a Spectrum Analyzer?

In this video I will be stepping through he process of how to get ready to use and how to use a Spectrum Analyzer.
You must answer 5 questions in preparation for your measurement. I will discuss how to answer these questions.
I will explain
How to set up the frequency limits
Adjust the RBW and VBW
Use markers
As part of this who process, I will also explain what dBm is and how to convert from and to dBm.

**** IMPORTANT NOTE: ****
The difference between signal levels MUST be expressed in dB, NOT dBm.
A +20 dBm signal is 0.1 Watts; a +10 dBm signal is 0.01 Watts. If I subtract 10 dBm from the +20 dBm signal, I get a 0.09 Watt signal which is +19.54 dBm.
