Performance Test

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 Table 19 when testing the E9325A, E9326A, and
E9327A. Use Table 20 when testing the E9321A, E9322A, and
E9323A.
