The Rohde & Schwarz FSH-K14 and Rohde & Schwarz FSH-K15 options make spectogram measurements possible. With the application for spectrogram measurements, the Rohde & Schwarz FSH provides a history of the spectrum. It enables the analysis of intermittent disturbances or fluctuations in frequency and level as a function of time. The replay of recorded data as well as the setting of time lines and markers enable a targeted evaluation. The Rohde & Schwarz FSH can record measurements of up to 999 hours with an adjustable recording interval. A short recording interval increases the acquisition rate for the recording of very short interrupted signals. A recording can be started manually, with a predefined start and stop time and date, or can be triggered by other events.
With the compressed view in the Rohde & Schwarz InstrumentView software, a quick search for unclear signals is possible. The spectrum display at the bottom right in the screenshot can be enlarged for further analyzes.
