Abstract
A reflectometer for use in measuring scattering (S-) parameters for a device under test (DUT) includes a test port, a radio frequency (RF) output signal source, and a local oscillator (LO) signal. The LO signal is used to downconvert the RF output signal to an incident IF signal. The reflectometer is useable as a master reflectometer with a slave reflectometer such that the master reflectometer provides the slave reflectometer with a synchronization signal to synchronize signals generated by the second reflectometer to the incident IF signal. Phase and magnitude of transmission S-parameters of the DUT are measurable when the reflectometer is used as the master reflectometer in combination with the slave reflectometer. The master reflectometer and the slave reflectometer can be reconfigurable to reverse the master/server roles of the reflectometers.
