Complex RF Signals

The analysis capabilities of the Real-Time Spectrum Analyzer provide simultaneous time-correlated views of a signal in the frequency, time and modulation domains, enabling much faster resolution of complex problems that often occur in today’s RF systems.

By acquiring a record of real-time signal behavior, the Real-Time Spectrum Analyzer supports numerous powerful analysis tools. One example is the spectrogram display, which plots frequency and amplitude changes over time.

It provides an intuitive, three-dimensional display of the time-varying signal behavior, not seen in traditional frequency domain plots. This view makes it easy to see phenomena such as modulation switching, signal hand-offs, frequency hops and settling time between pulses, and changes in frequency over time.

In addition to providing time-correlated multi-domain analysis on a wide variety of signals, certain Tektronix Real-Time Spectrum Analyzers support the latest mobile and wireless data standards, as well as providing a general purpose digital modulation analysis on a wide variety of formats. With time-correlated views across the frequency, time and modulation domains and a full range of analysis capabilities, you gain unprecedented insight into RF signal behavior for complete characterization and quick problem-solving.
