•

DART Major Alarms

–

DART  Fault

—Summary alarm state of the DART card upconverter 

downconverter and the DART FPGA. Red indicates that either the clock 
source for the DART card is outside the acceptable range or the DART FPGA 
is not programmed. 

–

DART DC Supply Fault

—Red indicates DART card DC supply is faulted. 

–

DART  Hardware  Mismatch  Fault

—Red indicates an invalid passband 

configuration for the DART. 

–

DART  Over  Temperature  Fault

—Red indicates DART card internal 

temperature is too high. Fault threshold is 

84°C

.

–

DART  Remote  Ranging  Fault

—Red indicates that the Host is unable to 

implement the signal delay entered in the RF Band Configuration Page 
(described in 

“Link the Host and Remote DARTs.” on page 159

).

•

Power Detector Major Alarms

–

System  VSWR  Fault

—Red indicates a VSWR fault at the interface to the 

antenna (greater than 3:1).

–

RF Power Fault

—Red indicates that the RF power measured at the antenna 

output is too low. The threshold for this fault is 

0 dBm
