The R&S®FSVR combines a full-featured signal and spectrum analyzer with a real-time spectrum analyzer. Therefore, it provides all the capabilities and features that modern T & M instruments of this kind have to offer. In real-time operation, the R&S®FSVR seamlessly measures and displays the spectrum in the time domain with a span of up to 40 MHz. As a result, it captures every event for analysis, no matter how brief that event might be.

Interference caused by sporadic and brief events in the frequency domain, by the spectral behavior of signal sources during frequency switching or by the influence of digital circuits on RF signals present a problem familiar to all development engineers and service technicians who work in the field of RF engineering. Pinpointing the cause of such problems is usually a difficult and time-consuming chore. In such situations, the R&S®FSVR's unique capabilities for capturing and displaying RF spectra in real-time help to analyze faults and characterize signals quickly and easily. It seamlessly measures the signal spectrum in real-time, and even with a time overlap. For visual evaluation, it offers a spectrogram in addition to the instantaneous spectrum in real-time in persistence mode, it visualizes the real-time spectrum with color coding that indicates how often a signal occurs. Frequency-dependent masks provide support when triggering on spectral events. This makes it possible to reliably detect signals that occur sporadically in the spectrum and to investigate them effectively.

Besides its real-time capabilities, the R&S®FSVR offers all functions of the R&S®FSV signal and spectrum analyzer.
