Digital circuit power integrity test system configuration and key performance indicators

High-speed digital circuit power integrity measurement has always been a difficult problem. Previously, most R&D units and companies did not measure these power integrity parameters. However, as the digital signal rate continues to increase, especially after it reaches the order of magnitude above 10Gbps, the measurement of power integrity has become one of the key test items. As a result, customers have been constantly inquiring about test solutions for power integrity recently, so now the configuration and key performance indicators of the power integrity test system are sorted out as follows.
