This paper presents an 8-port 10 MHz - 110 GHz vector network analysis measurement setup, achieving high magnitude accuracy by using two separate commercially available network analyzers with frequency extenders. Compared to a single VNA setup, the approach achieves a maximum absolute linear magnitude error of less than 0.05 up to 90 GHz. The paper describes the necessary hardware interconnects, along with the proposed software algorithm. The attained accuracy and dynamic range are demonstrated to be suitable for the 8-port characterization of crosstalk in densely packed signal routing environments, such as terabit-per-second chip-to-chip interfaces, extending to a higher frequency range than what is currently commercially available.
