10. A device for detecting noise parameters, the device comprising:
a noise source;
a recirculator coupled to the noise source;
a device under test (DUT) coupled to the recirculator, wherein the DUT is configured to generate a first noise power and a second noise power, wherein the DUT is configured to be replaceable;
a first power detector coupled to the recirculator and further coupled between the noise source and the DUT, wherein the recirculator is configured to direct the first noise power to the first power detector; and
a second power detector coupled to the DUT, wherein the DUT is configured to direct the second noise power to the second power detector, wherein the device is configured to determine a noise figure from the noise source to the first power detector based on a correlation matrix of noise parameters for the DUT.
