TLC labmaster 10zi a25 September 2020 – Teledyne LeCroy announced that the LabMaster 10 Zi-A real-time oscilloscope and Anritsu Signal Quality Analyzer-R Series MP1900A have been approved by the USB Implementers Forum (USB-IF) for USB4 electrical physical layer transmitter (Tx) and receiver (Rx) compliance certification testing.

By establishing compliance programs to complement the USB specifications, the USB-IF sets the stage for seamless interoperability between USB host and peripheral devices. For electrical or physical layer testing, the USB-IF approves test equipment that they have confirmed meets the requirements of the electrical compliance test specification (CTS) before the equipment can be used for USB4 certification testing. Using approved test equipment for compliance testing of a USB4 host or device supports developers looking to achieve certification for their USB4 products. Certification supports a good end-user experience and can lead to wider market adoption.

Teledyne LeCroy has worked closely with the USB-IF for approval of the LabMaster 10 Zi-A oscilloscope (with SDAIII-CompleteLinQ and QPHY-USB4-TX-RX software packages) for Tx testing. QPHY-USB4-TX-RX software fully automates Tx and Rx testing for enhanced speed and error-free user setup. Automated Rx calibration and testing uses the Anritsu MP1900A as the stressed signal generator. Teledyne LeCroy continues to work closely with the USB-IF, independent test labs (ITLs) and developers to ensure accurate USB4 Tx and Rx certification test results. QPHY-USB4-TX-RX also supports Thunderbolt testing, and the same equipment has been approved by Intel for required Tx and Rx testing.

“Teledyne LeCroy is a long-time vendor of both physical and protocol layer test solutions used at USB-IF compliance workshops and by USB-IF ITLs,” said USB-IF President and COO Jeff Ravencraft. “We are pleased with Teledyne LeCroy’s continued commitment to provide approved test solutions that help our members develop certifiable USB products in support of a robust, reliable USB ecosystem.”
