The intent of this test is to measure the response of impulsive signals to the CW amplitude. What makes this test unique to the CISPR amplitude relationship test is the PRF is set very low (0.625 Hz). The modulated signal is defined by CISPR 16-1-1 as an RF Pulse (as compared to the DC pulse for the Quasi-Peak measurements). CISPR 16-1-1:2019 defines the Impulse Area of an RF pulse in Section 7.3.3 (Average Detector) and Section 8.3.4 (RMS-Average Detector). For this test CISPR defines the Pulse width as 160 ms for Bands A, B, and 100 ms for Bands C, D, and E. For this test, CISPR defines the pulse period as 1.6 seconds, or 0.625 Hz. The source amplitude is not critical as this is a relative measurement between the CW amplitude and the pulsed amplitude.
