True Multiport Measurements for USB Type-CTM Cable Assembly

Driven by the demand for more bandwidth, high-speed digital standards continues to evolve to higher data rates. The 10 Gbps USB 3.1 specification delivers more than double the practical data rate compared to the current 5 Gbps USB 3.0. This increase in data rate results in even tougher requirements for the physical layer to ensure interoperability.

One of the measurement challenges for such high-speed digital cable assemblies is to perform the multiport measurements. Keysight M937xA PXI Multiport Vector Network Analyzer provides the true multiport measurements with full n-port calibration and its inherent frequency domain measurement capability. For the USB Type-CTM cable assembly tests, M937xA can be configured to support 12-port measurements from 300 kHz to 15 GHz to generate an s12p touchstone file analyzed by the USB-IF compliance tool.

Measurement Correlations between M937xA and E5071C

For the cable assembly compliance tests, Keysight E5071C ENA Option TDR has been certified for various high-speed digital standards

such as USB, HDMI, DisplayPort. As shown below, the measurement results are well correlated between M937xA PXI Multiport Vector

Network Analyzer and E5071C ENA Option TDR when comparing the USB Type-C cable assembly measurement results.
