Radiated Band Sine Wave Accuracy Performance Test

The Sine Wave Accuracy measurement is broken into two tests: Radiated Band Sine Wave Accuracy and Conducted Band Sine Wave Accuracy. The reason for splitting the measurement into two tests is source utilization.

In this test a 30 MHz to 18 GHz signal is applied to both the EMI receiver and a power meter. For each test frequency, the amplitude is measured with the power meter and the DUT. The EMI System Sine Wave Accuracy is the difference between the two amplitudes.
