Table 23: RF System Alarms When Faulted
ALARM NAME DESCRIPTION
Oper Mode Operating mode is not “Norml.” For a description of other
modes, see Topic 4.1.4, Tools Menu, on page 60.
System VSWR Voltage Standing Wave Ratio measured at the duplexer is too
high.
Table 24: Linear Power Amplifier Alarms When Faulted
ALARM NAME DESCRIPTION
LPA Detect The LPA is “not present” when read (physically not there).
LPA Disable The LPA has been disabled due to an alarm.
LPA DC Fail LPA DC power is faulted.
LPA Loop Faulted LPA has an internal loop failure.
LPA Low Power RF output signal level measured in LPA is too low.
LPA VSWR Voltage Standing Wave Ratio measured in LPA is too high.
LPA Fan LPA fan is faulted.
LPA Temp LPA temperature is too hot.
Table 25: RF Levels Display
ALARM NAME DESCRIPTION
RF Power If alarmed (red), indicates that the RF output signal measured
in LPA is too low.
RF Output Power Current level of RF output signal as measured in LPA. The
accuracy of this readout is +/-3 dB. If a more accurate
measurement is needed, measure at the remote unit.
Current VSWR Current reading of the Voltage Standing Wave Ratio.
Remote Fwd Att Current attenuation setting for forward path RF signal.
Clicking on Edit button displays a dialog used for setting the
remote forward path attentuation. For more information on
setting attenuation, refer to Topic 3.11 on page 44.
