The MS46500B series consists of 2-port MS46522B and 4-port MS46524B models. The 500B series VNAs bring the highest level of performance to the ShockLine family. These VNAs have Industry best 140 dB dynamic range and are faster than the older generation “A” series models. The 500B series features an independent source per VNA port. These VNAs have a unique capability, which allows all the sources to sweep at the same time, resulting in a measurement of all s-parameters in a single sweep. This simultaneous sweep significantly improves the sweep time over “A” model VNAs.
