Performance Verification Tests
33. Gain Compression: Agilent E4401B, E4402B, E4403B, and E4411B

7. Record the actual synthesized sweeper power level setting in

Table 2-77 for each frequency indicated.

8. Repeat step 3 through step 7 for each of the settings listed in

Table 2-77. The test at 50 MHz with a span of 1 kHz, is only for the

E4401B and E4402B with Option 1DR.

9. Disconnect the power sensor from the directional bridge and connect

the directional bridge to the input of the analyzer using an adapter.

Do not use a cable.

75 Input only: Use a 75 adapter, Type-N (m) to BNC (m) and a

mechanical adapter, Type-N (m) 50 to Type-N (f) 75
