Tektronix RSA3303A Real-Time Spectrum Analyzer captures many signals not viewable on swept spectrum analyzers by seamlessly capturing and storing a span of RF frequencies all at one time. Once a signal is captured it can be viewed simultaneously and analyzed in time-correlated frequency, time and modulation domains. The RSA3303A instrument includes 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. Trigger, Capture, Analyze 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. RSA Series Spectrogram uniquely shows time-varying signal behavior in frequency change/stability, spectrum occupancy, pulsed signal timing, power change and more. 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-topulse phase variation measured in the modulation domain.
