Performance Verification Tests
22. Frequency Response: Agilent E4401B and E4411B
Additional Equipment for 75 Ω Input
Power sensor, 75 Ω
Minimum Loss Pad, Type-N (f) 75 Ω to Type-N (m) 50 Ω
Adapter, Type-N (m) to BNC (m), 75 Ω
CAUTION Use only 75 Ω cables, connectors, or adapters on instruments with 75 Ω
connectors, or damage to the connectors will occur.
Procedure
Source/Splitter Characterization
1. Connect the equipment as shown in Figure 2-26. Connect one of the
Agilent 8482A power sensors to Channel A of the power meter. This
will be the “reference” sensor. Connect the other Agilent 8482A
power sensor to Channel B of the power meter. This will be the
“buried” sensor.
75 Ω Inputs, Option 1DP: Connect the Agilent 8483A power sensor to
Channel A of the power meter. This will be the “reference” sensor.

2. Zero and calibrate both power sensors.
3. On the power meter, set the Channel A calibration factor to the
