  • Anritsu’s testing solution aims to handle the large data volumes driven by next-gen 5G communications and IoT technology
  • Performs accurate measurement of high-speed computing and data communications interfaces

Anritsu Corporation has released its USB4 receiver test solution, which uses 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.

Next-generation 5G mobile communications and the Internet of Things (IoT) devices are driving the 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 further extended to USB4 for offering doubled speeds of 20 Gbit/s x 2 lanes.

Due to the 20-Gbit/s speed of USB4, electrical tests emphasise heavily on the pulse rise time/fall time (Tr/Tf) and intrinsic jitter performance of the test signal source because measurement-system noise and jitter cannot be ignored.

Additionally, 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 Bit Error Rate Tester (BERT) and oscilloscope combination is necessary to minimize the workload of signal calibration and optimize test reproducibility.

High performance testing equipment

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 produce a more accurate measurement of high-speed USB performance (as required by the USB4 receiver test).

Also, 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.
