Performance Verification Tests
20. Overall Absolute Amplitude Accuracy: Agilent E4402B, E4403B, E4404B, E4405B, E4407B,
and E4408B
be used for the 4 dB setting on the 1 dB step attenuator.
10.Calculate the actual total attenuation by adding the actual
attenuation for the 1 dB step attenuator to the actual attenuation for
the 10 dB step attenuator for each total attenuation setting listed in
Table 2-34.
NOTE The external attenuators and cables are now part of the “source.”
11.Adjust the signal generator amplitude for a power meter reading of
0dBm
±0.2 dB. Record the power meter reading here:
Amptd0dBm = _______ dBm
12.Connect the equipment as indicated in Figure 2-24. The fixed
attenuator must connect directly to the analyzer input.
