Long-period noise capture performance evaluation system and long-period noise capture performance evaluation method

摘要

To provide a long-period noise capturing performance evaluation system capable of evaluating a long-period noise capturing performance by an actual measurement, and to provide a comb generator capable of generating a reference signal for simulating a long-period noise by the evaluation system.SOLUTION: When observation time of a receiver 5 included in an EMC measurement system is D, a burst including a plurality of pulses having a pulse period tof a reciprocal of a spectrum peak interval 1/tis continuously transmitted at a burst period T in which T is larger than D from a comb generator 21 for generating a reference signal, the reference signal is measured for a plurality of times by the EMC measurement system, and it is measured whether the EMC measurement system captures a long-period noise normally from a ratio of the number of reception times of the reference signal to the number of measurement times.SELECTED DRAWING: Figure 1
