Error and Warning/Status Messages Operator Maintenance
Error Message Description/Remarks
Error 130
2 – 3.3 GH Switched Filter
Indicates a failure in the 2 to 3.3 GHz switched filter path within the switched filter
assembly. The MG369XB may not produce an RF output in this frequency range.
Use caution and always determine the output power level when operating the
MG369XB in this condition.
Error 131
3.3 – 5.5 GH Switched Filter
Indicates a failure in the 3.3 to 5.5 GHz switched filter path within the switched filter
assembly. The MG369XB may not produce an RF output in this frequency range.
Use caution and always determine the output power level when operating the
MG369XB in this condition.
Error 132
5.5 – 8.4 GH Switched Filter
Indicates a failure in the 5.5 to 8.4 GHz switched filter path within the switched filter
assembly. The MG369XB may not produce an RF output in this frequency range.
Use caution and always determine the output power level when operating the
MG369XB in this condition.
Error 133
8.4 – 13.25 GH Switched Filter
Indicates a failure in the 8.4 to 13.25 GHz switched filter path within the switched fil
-
ter assembly. The MG369XB may not produce an RF output in this frequency
range. Use caution and always determine the output power level when operating
the MG369XB in this condition.
Error 134
13.25 – 20 GH Switched Filter
Indicates a failure in the 13.25 to 20 GHz switched filter path within the switched fil-
ter assembly. The MG369XB may not produce an RF output in this frequency
range. Use caution and always determine the output power level when operating
the MG369XB in this condition.
Error 135
Modulator or Driver Failed
Indicates a failure of the modulator in the switched filter assembly or the modulator
driver circuitry. The MG369XB may not produce an RF output. Use caution and al-
ways determine the output power level when operating the MG369XB in this condi
-
tion.
Error 136
SQM Unit or Driver Failed
Indicates a failure of the source quadrupler module (SQM) or SQM bias regulator
circuitry. The MG369XB is still operable, but it may not produce an RF output in the
frequency range above 40 GHz.
Error 138
SDM Unit or Driver Failed
Indicates a failure of the switched doubler module (SDM) or SDM bias regulator cir
-
cuitry. The MG369XB is still operable, but it may not produce an RF output in the 20
to 40 GHz frequency range.
Error 139
32 – 40 GHz SDM Section Failed
Indicates a failure in the 32 to 40 GHz switched doubler filter path within the SDM.
The MG369XB is still operable, but it will not produce an RF output in the 32 to
40 GHz frequency range.
Error 140
25 – 32 GHz SDM Section Failed
Indicates a failure in the 25 to 32 GHz switched doubler filter path within the SDM.
The MG369XB is still operable, but it will not produce an RF output in the 25 to
32 GHz frequency range.
Error 141
20 – 25 GHz SDM Section Failed
Indicates a failure in the 20 to 25 GHz switched doubler filter path within the SDM.
The MG369XB is still operable, but it will not produce an RF output in the 20 to
25 GHz frequency range.
