Tektronix - Guide to RF Signals
The eGuide to Signals will help you navigate the RF spectrum and gain a better understanding about what kinds of signals might be present around you. Detailed examples are provided for popular signals often transmitted over the air.
Examples of cellular, WLAN, P25, airport radar, and microwave ovens are provided. All signal examples have brief movies of the signals, measurements, audio recording of demodulated FM, and SignalVu-PC setup files and saved IQ waveforms.
Use this eGuide to help you understand what kinds of signals to expect to find, or to help you identify signals to separate legitimate signals from other signals.
