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: Step 1
