Making Adjustments: If 3335A Source Not Available
6a. Cal Attenuator Error
8. Set the analyzer’s reference level by pressing AMPLITUDE, 17, dBm.
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 Table
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 Table 2a-2.
2 dB Check
12.To measure the 2 dB step correction, press the following analyzer
keys.
AMPLITUDE, 16, dBm
13.Set the 1 dB step attenuator to 7 dB.
14.Press the following analyzer keys.
PEAK SEARCH, MARKER DELTA
MKR FCTN, MK TRACK ON OFF (ON)
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
AMPLITUDE, 14, dBm.
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 Table
2a-1.
2 dB attenuator step error =
Analyzer MKR - (7dB attenuator error - 5 dB
attenuator error)
19.Enter the 2 dB attenuator step error in Table 2a-2.
