Transmitter Distortion Test
전단지
Modern and future vehicles depend on rapid data communications within the car. Automotive Ethernet, while facilitating faster data transfer, must also ensure the swift transmission of large data volumes without introducing distortion that could compromise signal quality. The IEEE’s 100BASE-T1 and 1000BASE-T1 Transmitter Test Mode 4 provides a transmitter distortion test to confirm that the Ethernet’s transmitter distortion remains within a predefined threshold. This test measures the transmitter’s peak distortion, verifying its compliance with the specified limits. This tip explains how that test is done by Keysight equipment, offering two methods for the final measurement result.
