Standing Wave Ratio (SWR) and Reflection Coefficient (Rho)
Performance Test
This section does not establish preset SWR test procedures since there are several test methods and different equipment available for testing the SWR or reflection coefficient. Therefore, the actual accuracy of the test equipment must be accounted for when measuring against instrument specifications to determine a pass or fail condition. The test system used must not exceed the system Rho uncertainties shown in the following tables when testing the Agilent
