6a. Cal Attenuator Error
8. Set the analyzer's reference level by pressing
9. Set the 1 dB step attenuator to 8 dB.
10.The 1 dB attenuator step error is the MKR ∆ reading minus the
error in the 1 dB step attenuator when set to 9 dB and 8 dB in
2a-1.
1 dB atten step error =
Analyzer MKR ∆ - (9dB atten error - 8 dB atten error)
11.Enter the 1 dB attenuator step error in

15.The MKR ∆ amplitude reading should be 0.0 dB ±0.01dB. If it is not,
repeat step 5.
16.Set the analyzer's reference level by pressing
17.Set the 1 dB step attenuator to 5 dB.
18.The 2 dB attenuator step error is the MKR ∆ reading minus the
error in the 1 dB step attenuator when set to 7 dB and 5 dB in
2a-1.
2 dB attenuator step error =
Analyzer MKR ∆ - (7dB attenuator error - 5 dB
attenuator error)
