CAUTION Use only 75 Ω cables, connectors, and adapters on instruments with

75 Ω connectors, or the connectors will be damaged.

Procedure

Calculate the Actual Attenuation Errors

1. From the calibration data supplied with the 10 dB step attenuator,

enter into Column 4 of Table 2-13 through Table 2-17 the actual

attenuation for the corresponding nominal attenuation settings.

Enter data in Table 2-14, Table 2-16, and Table 2-17 only if the

analyzer has Option 1DR.

If the calibration data does not indicate an actual attenuation value

for the 0 dB setting, enter 0 dB.

NOTE The Agilent 8496G programmable attenuator has four attenuator

sections consisting of 10 dB, 20 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. From the calibration data supplied with the 1 dB step attenuator,

enter into Column 5 of Table 2-13 through Table 2-17 the actual

attenuation for the corresponding nominal attenuation settings.

Enter data in Table 2-14, Table 2-16, and Table 2-17 only if the

analyzer has Option 1DR.
