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 FSVRs 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.
