Which signal has which characteristic, which spectrum? What is typical, what is correct, what is due to interference? The Signal Guide provides an overview of »Radio Services« and »Modulation Types« associated with them, and explains their characteristics using images of typical signals. These were measured with Narda's Interference and Direction Analyzer IDA 2. The results are nevertheless generally applicable.
Select »Radio Services« or »Modulation Types« to access the examples and explanations, or use the »Gallery« to display the signal images, which you can compare with the measurement results you have obtained, for example. You will also find examples of how to recognize interference there. The »Glossary« explains important technical terms being used.
