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 U2000 Series USB power sensors.
