Spectrum analysis: Parallel operation: correlation between frequencyand time identify interactions Advanced electronics is based on the seamless interaction between protocol-based interfaces, digital, analog and fre- quency components. Simultaneous analysis of all compo- between time and nents is a must. Time, frequency and protocol information is correlated, and time references can be quickly recog- nized. Measurement windows help you select specific ar- frequency eas of the recording, which can simplify, for example, the acquisition of frequency switching operations. Spectrogram: display of frequency over time A spectrogram displays the spectrum of frequencies as they vary over time. For easy interpretation, the magni- tude can be color-coded. Thanks to the high FFT rate, even Spectrogram: fast frequency changes can be displayed. When used in evolution over time combination with the history and segmented memory, the spectrogram marker shows the time of the acquisition Peak markers: and makes it possible to load the corresponding time and frequency waveforms onto the screen. All R&S®RTA4000 automatic positioning tools can be used to analyze the loaded waveforms. Markers: find peaks automaticallyFast and precise analysis Markers can be automatically positioned on the frequency Difficult-to-find faults often result from the interaction be- peaks for fast analysis. An adaptable threshold defines the tween time and frequency signals. The R&S®RTA-K18 1) peaks. Parameters such as excursion and maximum peak spectrum analysis and spectrogram option quickly finds width can be adjusted for in-depth analysis. Results can be such errors. Like on a spectrum analyzer, parameters compiled in a table (absolute or relative to a specific refer- such as center frequency and resolution bandwidth can ence marker). Selectable delta measurements make it easy be adapted to the specific measurement task.

Optimum performance ensures the fastest multi- domain analysis in this oscilloscope class. 1) The R&S®RTA-K18 option is not distributed in North America.
