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
Ω Input only: Use a 75 Ω adapter, Type-N (m) to BNC (m) and a
mechanical adapter, Type-N (m) 50
Ω to Type-N (f) 75 Ω
