Trigger, Capture, Analyze Your RF Signal

Quickly Solve Design, Production or Operational Problems With Comprehensive Characterization of Time-varying and Transient RF Signals

Define issues and solve problems faster by characterizing your device, system or signal more completely and rapidly than previously possible with swept spectrum analyzers. Tektronix RSA3300A Series Real-Time Spectrum Analyzers capture many signals not viewable on swept spectrum analyzers by seamlessly capturing and storing a span of RF frequencies all at one time*1. Once a signal is captured it can be viewed simultaneously and analyzed in time-correlated frequency, time and modulation domains. RSA Series instruments include not only Real-Time Spectrum Analyzer fast-signal capture, internal memory and modulation analysis but also functionality and operation of a swept spectrum analyzer for looking at very wide spans, all in an integrated, transportable package.

RSA Series Spectrogram uniquely shows time-varying signal behavior in frequency change/stability, spectrum occupancy, pulsed signal timing, power change and more! The sample on this page shows the frequency settling characteristic of a transmitting device.

Time-correlated multi-domain view provides a new level of insight about design or operational problems and possible solutions. The example on this page includes frequency, time, and modulation domain views of an AM-modulated pulsed signal with pulse-to-pulse phase variation measured in the modulation domain.

Trigger, Capture, Analyze
You Can Easily Catch an Elusive RF Signal and Analyze It at Your Convenience

Sensitive and fast, RSA Series Real-Time Spectrum Analyzer triggering easily captures unknown, periodic or intermittent signals. Using the Tektronix exclusive Frequency Mask Trigger, you can configure a custom frequency domain mask including signal guard bands and levels then trigger on events isolated to a specific frequency or frequency range. As signals are captured, they are automatically saved to RSA internal memory, making it easy to perform in-depth, time-correlated analysis across the frequency, time and modulation domains with no external computer required! Quick-to-set-up IF Level and Power (Span Bandwidth) triggers provide very convenient capture of signals in applications such as incident carrier-and-response interaction between two devices or burst signal carrier ramp up. Continuous Trigger Mode ensures a sequence of events are automatically captured into memory; you capture only the events and not time in between, maximizing memory efficiency and minimizing analysis time.
