Receiver test solution supports USB4 Version 2.0 with 80Gbit/s data transmission speed

Anritsu Corporation has introduced a receiver test solution that supports the latest USB4 Version 2.0 (USB v2) communication standard with 80Gbit/s data transmission speed. This was accomplished by improving the functionality of the Signal Quality Analyzer-R MP1900A. The company is contributing to the growth of USB4 v2 because this solution allows the evaluation of USB devices that transfer large amounts of data, such as HD video, etc.

The increasing demand for the high-capacity transmission of 4K/8K HD video and high-speed communication between AI-based IoT devices requires faster data transfer speeds. Faster USB communication has become essential to support the communication between smartphones, tablet PCs, and peripheral devices. The latest USB4 v2 data transfer speed is twice as fast as the previous USB4 v1. Therefore, high-speed video transfer to the display or storage drive via a USB Type-C cable is smoother.

The higher Baud rate and the use of PAM3 modulation may incur issues such as decreased communication speed and degraded communication quality due to the high-frequency noise and jitter generated during USB communication. Therefore, USB4v2 receiver evaluations require higher-quality signals than the USB device data transmission standard.

The pattern generator is also needed to simulate and evaluate bad communication quality conditions by adding noise and jitter to high-quality signals.

The MP1900A is a high-performance BERT that supports the receiver testing of high-speed computing and data communications interfaces, such as USB, PCIe, Thunderbolt and 400 GbE/800 GbE.

The existing MP1900A, which supports USB 3.2 and USB4 v1 receiver tests, can be upgraded to USB4 v2 by adding the new option and PPG module.

The PAM3 output signal from this module can be used for reliable receiver testing due to its low jitter and high-quality waveform performance. It also supports the Receiver Frequency Variation Training Test added to the USB4 v2 compliance test specification to evaluate the training function and establish stable communication conditions during USB connection.

The company will display the Signal Quality Analyzer-R MP1900A at ECOC 2024 at its stand C1.
