  • Method of determining a relative phase change of a local oscillator signal and method of determining a relative phase change of a radio frequency signal
    Patent number: 10659177
    Abstract: A method is provided that determines a relative phase change of a local oscillator signal. A method of determining a relative phase change of a RF signal is also provided. Generally, the methods described ensure that the effect of a swept local oscillator frequency on the measurements can be identified, particularly quantified. Hence, the effect can be considered in the error correction model applied later such that the measurement equipment can be calibrated appropriately.

  • Network analyzer systems and methods for operating a network analyzer
    Patent number: 10469333
    Abstract: A network analyzer system includes a network analyzer having at least two ports, a first operational device connected a first port of the at least two ports of the network analyzer and configured to perform a first task with the network analyzer, and a second operational device connected a second port of the at least two ports of the network analyzer and configured to perform a second task with the network analyzer. The second task is performed at least partially concurrently with the first task.
