In this test the amplitude of a pulse modulated signal is measured while varying the PRF (Pulse Repetition Frequency). The amplitude relationship is relative to a reference PRF as defined in the CISPR 16-1-1 document. 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). The Average Detector response is measured +/-1 PRF setting from the reference PRF. For the Average Detector, the reference PRF is 25 Hz (Band A), 500 Hz (Band B), 5000 Hz (Band C/D), and 50,000 Hz (Band E). For the RMS-Average Detector, the test PRFs are defined in Table 12 (2019 Edition). For each test, PRF the relative amplitude is compared to the CISPR limit.
