Performance Verification Tests
17. Absolute Amplitude Accuracy (Reference Settings): Agilent E4401B and E4411B
equipped with Option 1DS, Preamplifier.
Part 1. Splitter/Attenuator Characterization
Figure 2-17 Power Splitter/Attenuator Characterization Setup
1. Refer to Figure 2-17. Connect one RF power sensor to Channel A of
the power meter. This will be the “reference” sensor. Connect the
other RF power sensor to Channel B of the power meter. This will be
the “buried” sensor.
75
Ω Inputs, Opt 1DP: Connect the 75Ω 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
reference sensor’s reference calibration factor.
4. On the power meter, set the Channel B calibration factor to 100%.
Do not change this calibration factor during this test.
5. Connect the equipment as shown in Figure 2-17, “Power
Splitter/Attenuator Characterization Setup,”. Use the 20 dB fixed
attenuator for 50
Ω analyzers. Use the 10 dB fixed attenuator and
the minimum loss pad for 75
Ω analyzers. Note that the reference
sensor connects to either the fixed attenuator (50
Ω analyzers) or the
minimum loss pad (75
Ω analyzers).
6. Set the synthesized signal generator frequency to 50 MHz and
amplitude to +12 dBm
