Signal Quality Analyzer supports USB4 Receiver Test

Anritsu MP1900A26 June 2020 – Anritsu Corporation announced the start of sales of its USB4TM receiver test solution using the company's Signal Quality Analyzer-R MP1900A in combination with automation software from Granite River Labs or Teledyne LeCroy to control a connected oscilloscope and implement tests meeting the latest USB4 standards.

The spread of next generation 5G mobile communications and Internet of Things (IoT) devices is driving development of various new communications and IoT services that are massively increasing data volumes. To increase the speed of interfaces handling these large video and data files, smartphones, tablet PCs, and other digital devices are adopting USB Type-C connectors. These connectors are an extension of the USB 3.2 high-speed standard (10 Gbit/s x 2 lanes), which has now been extended again to USB4 offering doubled speeds of 20 Gbit/s x 2 lanes; USB4 compliance tests are being run in 2020.

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. Additionally, like previous USB tests, to assure accurate measurement of device receiver sensitivity, the test is performed by calibrating the test signal according to the minimum input performance defined by the receiver standards. Automation of the BERT and oscilloscope combination is necessary to minimize the workload of signal calibration and optimize test reproducibility.

The Signal Quality Analyzer-R MP1900A is a high-performance BERT supporting not only USB tests, but also receiver tests of high-speed computing and data communications interfaces, such as PCI Express, Thunderbolt, and 400 GbE/800 GbE.

Its high-quality 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. In addition, combination with Granite River Labs GRL-USB4-RXA or Teledyne LeCroy QPHY-USB4-TX-RX (USB4/TBT3 transmitter and receiver) automation software for automating signal calibration and testing helps high-reproducibility measurement of USB4 interfaces according to the latest standards while also reducing test workload.
