Anritsu Company enhances its Signal Quality Analyzer-R MP1900A to support the latest USB4® Version 2.0 (USB v2) communication standard of 80 Gbit/s data transmission speed. The new functionality of the MP1900A allows the analyzer to serve as a receiver test solution that enables accurate, repeatable evaluation of USB devices that transfer large amounts of data, such as HD video, to support the implementation of USB4 v2 in emerging designs. 

Increasing demand for high-capacity transmission of 4K/8K HD video and high-speed communications between AI-based IoT devices require high-speed data transfer. Faster USB transmission is necessary to support communications between mobile devices and PCs and peripheral devices. The latest USB4 v2 data transfer speed is twice that of USB4 v1, for efficient high-speed video transfer to the display or storage drive via a USB Type-C® cable.

The MP1900A has been enhanced to address the higher Baud rate and PAM3 modulation associated with USB4v2. It produces a high-quality signal to conduct accurate high-frequency noise and jitter analysis to evaluate USB4v2 receivers to ensure they are compliant with the USB device data transmission standard.  

Reliable receiver testing is assured due to the low jitter and high-quality waveform performance of the PAM3 signal outputted by the MP1900A’s built-in pulse pattern generator (PPG). The PPG module allows the analyzer to simulate and evaluate poor communication quality conditions by adding noise and jitter to high-quality signals. It also supports the Receiver Frequency Variation Training Test added to the USB4 v2 compliance test specification to evaluate the training function to establish stable communication conditions during USB connection.

Support for USB4 v2 expands the comprehensive analysis capability of the MP1900A. A high-performance BERT, the MP1900A also supports receiver testing of all other major high-speed computing and data communications interfaces, such as legacy USB, as well as 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.
