SFC6400A/SFC1450A Synthesized Frequency Upconverter User Interfaces
TM106 – Rev. 1.1 4-11
Backup Test is done when the <LEARN> function is
initiated. The SW Fault will flash at one-second intervals
to flag this fault to the user.
CFG CHGD FAULT: {PASS, FAIL/UNMASKED, MASKED}
backup converter only. Indicates that the configuration of
one or more Prime Converters has changed since being
learned by the Backup. Note that the Backup
continuously monitors the settings of all Prime Units in
the system to determine if anything changes. The SW
Fault will flash at one-second intervals to flag this fault to
the user.
RF DTECT FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a failure when the detected RF input signal falls
below a fixed threshold.
IF DTECT FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a failure when the detected IF signal falls below
a fixed threshold.
COMMON:
CPLD FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the Controller PCB Microprocessor
reads back an unexpected value from the CPLD. This is a
check performed on system power up.
FPGA FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the Controller PCB microprocessor
reads back an unexpected value from the FPGA. This is
also a check performed on system power up.
EEPROM FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the Controller PCB microprocessor
reads back an unexpected value from the EEPROM. This
is checked on system power-up, but is also monitored
during normal operation.
REFERENCE ACT: {PASS, FAIL/UNMASKED, MASKED}
A failure indicates that there is no signal connected to the
External Reference input on the back panel. In this
condition, the Converter uses the internal reference
oscillator.
VCC1 FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the +5V Supply Voltage of the
Controller PCB Microprocessor is outside a fixed range.
+9V FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the +9V System Supply Voltage is
outside a fixed range.
+15V FAULT: {PASS, FAIL/UNMASKED, MASKED}
