The analysis capabilities of the Real-T
ime 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.
