RSA2200A and 3300A Series Real-Time Spectrum Analysers

Define issues and solve problems faster by characterising your device, system or signal more completely and rapidly than previously possible with swept spectrum analyzers. Tektronix RSA2200A and RSA3300A Series Real-Time Spectrum Analysers capture many signals not viewable on swept spectrum analysers 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. RSA Series instruments include not only Real-Time Spectrum Analyser fast-signal capture, internal memory and modulation analysis but also functionality and operation of a swept spectrum analyser for looking at very wide spans, all in an integrated, transportable package.

Trigger, Capture & Analyse

The RTSA offers unmatched synergy between triggering, capture, and analysis features. This balance is essential for dealing with today’s complex RF signals: powerful triggering enables qualified capture; seamless capture and memory enable storage of a continuous time record; extensive analysis tools provide correlated views of frequency, time and modulation.

Powerful triggering has long been the missing ingredient in traditional swept spectrum analysers. The RTSA is the first mainstream spectrum analyser to offer frequency-domain triggers and other useful modes in addition to simple free run or external triggers. The Frequency Mask Trigger allows the user to set up both amplitude and frequency conditions for an acquisition.

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.

The Spectrogram clearly shows the behavior of a frequency hopping signal. A signal characteristic that can’t be seen with swept SA. The RTSA’s seamless capture with deep memory can acquire and record RF and time domain signal data for post-capture analysis.

The Frequency mask trigger allows you to capture elusive transients in a crowded spectral environment. The Spectrogram aides in identification and analysis of hidden, unknown or interfering signals. Notice the fourth signal from the left. It triggers the acquisition by leaving the mask. It’s time history can be seen on the Spectrogram. Unlike the swept SA, the RTSA is able to capture a glitch anywhere in the span, any-time. The Frequency Mask Trigger can be set to ignore the "normal" signal frequencies, ignore low-level aberrations, and trigger only when an anomaly exceeds a specific power level.
