The analyzers differ in frequency range, unidirectional or bidirectional measurement capabilities, active or passive test set, number of reference channels and thus availability of calibration techniques.
ZVM and ZVK are compact instruments with integrated generator, two reference and two receiver channels and a bidirectional test set. This can be extended by attenuators with integrated switches in the generator and receiver paths. With this configuration, ZVM and ZVK offer direct access to all reference and receiver channels. This concept makes ZVM and ZVK well equipped for complex test setups, for example for bidirectional measurements on power amplifiers.
