Abstract
A method of synchronizing a reference oscillator frequency of a first network analyzer with a reference oscillator frequency of a second network analyzer through a device under test (DUT) includes measuring a drift in a transmitted signal measured at the second network analyzer. The method includes connecting the first network analyzer to a first end of the DUT and connecting the second network analyzer to a second end of the DUT. A local oscillator (LO) signal of the first network analyzer is locked to a reference frequency of the first network analyzer. A LO signal of the second network analyzer is locked to a reference frequency of the second network analyzer. A RF signal is transmitted from the first network analyzer to the second network analyzer and an intermediate frequency (IF) of the transmitted signal is generated using the LO signal of the second network analyzer. The second network analyzer measures the transmitted IF signal.
