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 the following tables when testing the
Agilent E-series E9300 power sensors.
Table 3: Power Sensor SWR and Reflection Coefficient for the E9300A
Table 4: Power Sensor SWR and Reflection Coefficient for the E9301A
Caution DC voltages in excess of the maximum value (5 Vdc) can damage the
sensing diode.
