Easily identify out-of-limit device emissions Signal list, frequency scan, and active detector meters are displayed on a single screen for easy review of the measurement results. Continuously scan a speciied frequency range or scan and search for signals above a margin or limit and place them in the signal list. Use the simultaneous detector meters to continuously measure a selected signal while maximizing the amplitude. Measure all the signals with the search and measure function using up to three detectors. Choose between peak, quasi-peak, EMI average, or RMS average detectors. The measurement results are compared to regulatory agency limits in the delta to limit column.
