Frequency mask trigger (FMT) for triggering the measurement on individual, sporadic events in the spectrum

The FMT responds to events in the spectrum; the figure below shows the processing chain. The R&S®FSVR evaluates each individual spectrum in real-time mode so that no information is lost. If a spectrum violates the predefined mask, the R&S®FSVR triggers a response and stops the measurement either immediately or after a selectable follow-up period. The data collected in response to the trigger event remains available for detailed analysis.

As a result, the R&S®FSVR can analyze the influence of interference signals on transmitters very quickly. The same holds true for signals directly following a frequency hop.

The persistence mode creates a spectral histogram and is a valuable aid for examining signals that change over time. The R&S®FSVR can use this function, for example, to analyze the fast transient response behavior of synthesizers. Gapless visualization of all frequencies and amplitudes that occur, including probability weighting, conveys a completely new impression of the system's dynamic behavior in the spectral range. Users can see if fast frequency hops occur or if the amplitude changes significantly for brief periods of time. Effects like these can strongly influence the behavior of the entire system but are difficult to detect with conventional analyzers.

Power versus time for analyzing the length/time variance of signals

The power versus time function provides an overview of signals in the time domain. The R&S®FSVR generates a real-time display of the signal’s power versus time. When the end of the set time window is reached, the signal is displayed again from the beginning of the window without losing any timeslots. A time domain or frequency mask trigger can be used to trigger on specific events and obtain a stable image.
