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 equipm ent 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 4 when testing the E4412A, or in
Table 5 when testing the E4413A
