VNA tools boost signal integrity testing for high-speed designs

May 11, 2016 // By Graham Prophet
Anritsu has added testing options to its VectorStar and ShockLine vector network analyzers (VNAs), for advanced signal integrity test and verification. The VectorStar Eye Diagram and ShockLine Advanced Time Domain (ATD) enable channel diagnostics and model validation of high-speed digital circuit designs.

The company notes that as data rates continue to increase, signal channel characterization becomes increasingly challenging. The result is that VNAs are becoming more of a staple in signal integrity measurements, however, additional capabilities in processing and visualizing data are beneficial.


The VectorStar and ShockLine VNA families provide complementary capabilities that enable SI engineers to meet their measurement needs across a wide range of applications. VectorStar is Anritsu’s highest performance VNA product line and may be used by SI engineers with the most challenging design requirements. For example, some designers want their test systems to be able to include up to the 5th harmonic of their system clock. VectorStar offers 2- and 4-port broadband configurations from 70 kHz to 70 GHz, 110 GHz and 145 GHz with a single coaxial connection, supporting the latest digital data rates, including 25/28 Gbps and 43 Gbps. Anritsu’s ShockLine VNA family also has excellent performance, but less capability at a lower price for less demanding SI applications.
