Teledyne LeCroy, Inc. furthers its USB4 testing with the announcement of QualiPHY USB4 electrical transmitter (Tx) and receiver (Rx) compliance test software (QPHY-USB4-TX-RX) for its LabMaster 10 Zi-A and WaveMaster/SDA 8 Zi-B oscilloscopes used in conjunction with Anritsu’s Signal Quality Analyzer-R (SQA-R) MP1900A BERT. This announcement follows Teledyne LeCroy’s shipment of the only USB4 protocol analyzer in September of 2019.

The USB Type-C® connector is becoming the PC industry’s standard for converged high-speed data, display (video) and power delivery. USB Type-C delivers data, video and power over the same connector, simplifying connections. USB4 through USB Type-C doubles the speed of USB 3.2 and is expected to see adoption by PC, docking and USB peripheral makers.

The combination of Teledyne LeCroy’s QPHY-USB4-TX-RX software and oscilloscopes with an Anritsu SQA-R MP1900A BERT provides USB4 electrical validation and test engineers an integrated electrical test solution for automated compliance testing, ensuring faster time-to-market. Key features of Teledyne LeCroy’s USB4 electrical test solution include:

  • Automated Tx and Rx electrical tests outlined in the USB4 Router Assembly, USB4 Captive Device and Thunderbolt 3 Electrical Compliance Test Specifications – the first and only solution that provides this capability.
  • Multi-lane analysis capability, which performs acquisition, analysis and compliance tests on both Tx lanes simultaneously, greatly reducing compliance test time.

“The USB Implementers Forum (USB-IF) is pleased to see Teledyne LeCroy announce support for USB4 electrical testing,” said USB-IF President and COO Jeff Ravencraft. “An important contributor to the USB ecosystem, Teledyne LeCroy’s participation and support for USB4 electrical compliance testing will help our members deliver high-performing and reliable USB products to market.”

“Anritsu and Teledyne LeCroy share a common goal of providing engineers early availability of highly accurate and efficient test solutions required to verify their leading-edge designs. Our combined solution integrating the SQA-R MP1900A and Teledyne LeCroy oscilloscopes fills the market void for a complete USB4 electrical test system,” said Hiroyuki Takahashi, General Manager, Anritsu Corporation.

Teledyne LeCroy will demonstrate the QPHY-USB4-TX-RX software with a LabMaster 10-36 Zi-A (36 GHz oscilloscope) and an Anritsu SQA-R MP1900A BERT at DesignCon 2020 in Santa Clara, CA, in Teledyne LeCroy booth #513. The full presentation schedule is listed at

Pricing and Availability

QPHY-USB4-TX-RX will be available for LabMaster 10 Zi-A and WaveMaster/SDA 8 Zi-B oscilloscopes with bandwidths of 25 GHz or higher. QPHY-USB4-TX-RX will be priced at $9,995. Oscilloscope firmware and QualiPHY automated compliance test software releases supporting these functions will be available in February 2020.
