The Persistence Option for the Narda SignalShark enables advanced real-time spectral analysis by retaining and displaying past signal energy occurrences over time. This function is critical when trying to detect short-duration or intermittent signals that may be hidden during a standard real-time sweep.
By visualizing spectrum persistence, users can distinguish between constant and transient signals with high temporal resolution. The display shows how often a specific power level occurs at a given frequency, enabling users to identify low-duty-cycle or burst-type emitters that would otherwise be missed.
This option is highly valuable in environments with complex RF activity, helping in the analysis of communication systems, interference sources, and spectrum occupancy trends.
