CONTROL/INDICATOR FUNCTION
FREQUENCY SYNTHESIZER Indicates Frequency Synthesizer board rf output status. GREEN indicates normal rf
output; RED indicates low or no rf output.
BUFFER AMP Indicates buffer amplifier rf output status. GREEN indicates normal rf output; RED
indicates low or no rf output.
PREDRIVER Indicates predriver rf output status. GREEN indicates normal rf output; RED
indicates low or no rf output.
DRIVER
HIGH DRIVE GREEN indicates normal drive level. RED indicates excessive rf drive level to the
RF Amplifiers.
LOW DRIVE GREEN indicates normal drive level. RED indicates low rf drive level to the RF
Amplifiers.
RF AMP
FUSE GREEN indicates a normal, no fault condition. RED indicates a failure of an RF
Amplifier fuse.
TEMP GREEN indicates normal temperature of RF1. RED indicates excessive temperature
of RF1.
OUTPUT MONITOR
NETWORK VSWR GREEN indicates that there is no detected VSWR in the network filter; RED
indicates detected VSWR.
ANTENNA VSWR GREEN indicates there is no detected VSWR in the antenna. RED indicates detected
VSWR.
VSWR TEST, pushbutton Used to test operation of VSWR logic, result of test is displayed on VSWR TEST
indicator. When the pushbutton is depressed, the VSWR TEST indicator will turn
RED for 4 seconds. If it returns to GREEN, a successful VSWR TEST has been
performed. If it remains RED, a VSWR TEST has failed.
VSWR TEST indicator Indicates result of VSWR TEST. GREEN indicates VSWR protection logic is
functioning normally. RED indicates VSWR logic fault.
SUPPLY FAULT GREEN indicates normal operation. RED indicates a power supply failure.
