Procedure
Calculate the Actual Attenuation Errors
1. From the calibration data supplied with the 10 dB step attenuator,
enter into Column 2 of Table 2-24 through Table 2-27 the actual
attenuation for the corresponding nominal attenuation settings.
Enter data into Table 2-25 and Table 2-27 if the analyzer has Option
1DR. If no calibration data is supplied for 0 dB, enter zero.
NOTE The Agilent 8496G programmable attenuator has four attenuator
sections consisting of 10 dB, 20 dB, 40 dB and 40 dB attenuators. If
using the Agilent 8496G programmable attenuator, enter the
calibration data for the section three 40 dB step rather than the section
four 40 dB step.
2. To calculate the attenuation error at other nominal attenuator
settings, subtract the attenuation error at the other settings from
the reference attenuator error and enter the result in Column 3 of
Table 2-24 through Table 2-27. Enter data into Table 2-25 and Table
2-27 if the analyzer has Option 1DR.
