Anritsu demonstrated a USB4 receiver test solution using the company’s Signal Quality Analyzer-R MP1900A. Used in combination with automation software from Granite River Labs or Teledyne LeCroy, it can control a connected oscilloscope and implement tests meeting the latest USB4 standards. Due to the 20-Gbit/s speed of USB4, the electrical test places heavy emphasis on the Tr/Tf and intrinsic jitter performance of the test signal source, because measurement-system noise and jitter cannot be ignored.
The Signal Quality Analyzer-R MP1900A is a high-performance BERT supporting USB tests, as well as receiver tests of high-speed computing and data communications interfaces, such as PCI Express, Thunderbolt, and 400 GbE/800 GbE. Its data output performance (12-ps Tr/Tf, and 115-fs rms Intrinsic Jitter) helps assure more accurate measurement of high-speed USB performance as required by the USB4 receiver test.
