  • Abstract
    A new automatic parallel intermediate frequency (IF) vector substitution principle is implemented in a dual-channel microwave vector ratio meter. A greater than 120-dB dynamic range and 0.001-dB and 0.1° resolutions are provided. A combination of analog adaptive filtering and digital data processing provides short measurement times. Theoretical performance limitations are analyzed.
