Successful Modulation Analysis in 3 Steps
89600B Vector Signal Analysis Software
Application Note
Introduction: The When measuring or troubleshooting digitally modulated systems, it is tempting
to go directly to the digital demodulation tools. Making a random sequence of
Measurement and measurements on a system and watching for things that look wrong or question-
able can produce useful results, but important things can be missed and a great
Troubleshooting deal of time wasted on unproductive or inefficient measurement approaches.
Sequence A planned measurement sequence is the most reliable way to find the cause of
signal problems and reduces the chances that other important signal errors will
be missed. This application note presents a planned measurement and trouble-
shooting sequence that consists of three steps:
