Features:

• Spectrogram measurement option
• For FSH spectrum analyzers
• Enables the FSH to provide a history of the spectrum
• The spectrogram display shows the spectral density of a signal in the frequency domain and over time simultaneously
• Intermittent faults or variations in frequency and level versus time can be analyzed
• Specific evaluations can be made by replaying recorded data and setting timelines and markers

The spectrogram measurements application allows the R&S FSH to provide a history of the spectrum. As a result, intermittent faults or variations in frequency and level versus time can be analyzed. Specific evaluations can be made by replaying recorded data and setting timelines and markers.

The R&S FSH can record up to 999 hours. The recording interval is adjustable. A short recording interval results in an increasing capturing rate, which is suitable for capturing very short intermittent signals.

Recording can be initiated manually, with predefined start and stop date and time, or triggered by events. Using R&S InstrumentView, the compressed view on the left allows fast search of ambiguous signals and the spectrum display on the right bottom can be zoomed in for further analysis.

Time and frequency markers can be added during the post-analysis stage and for documentation. This long time recording spectrogram allows unmanned recording, collection of activities over a long period and facilitates post-analysis, which is useful for interference hunting and spectrum observation.
