The Agilent / HP 8510C Vector Network Analyzer makes broadband measurements from 45 MHz to 50 GHz in 2.4 mm coax, from 45 MHz to 65 GHz in 1.85 mm coax and from 33 GHz to 110 GHz in waveguide bands. This unit can measure the magnitude, phase and group delay of two-port networks to characterize their linear behavior.
