59. Comms Absolute Power Accuracy (Options BAC or BAH)
0.02 dB, then 1 dB Actual0dB is 0.02 dB. In this case RefAtten0dB is
0.05 dB.
8. Obtain the metrology data for the step attenuators at 50 MHz. Enter
the actual attenuation values for each attenuator setting as
indicated in Table 2-117, Table 2-118, Table 2-121, and Table 2-122.
9. 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 2-117, Table 2-118, Table 2-121, and Table 2-122.
NOTE The external attenuators and cables are now part of the “source.”
10.Adjust the signal generator amplitude for a power meter reading of
15 dBm ±0.2 dB. Record the power meter reading here:
Amptd15dBm = _______ dBm
11.Connect the equipment as indicated in Figure 2-78.
