User Interfaces SFC1800A Synthesized Frequency Upconverter
4-10 TM111 - Rev. 1.0
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}
Indicates a fault if the +15V System Supply Voltage is
outside a fixed range.
- 15V FAULT: {PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the -15V system supply voltage is
outside a fixed range.
LATCHED ALRM:
The Latched Alarm Menu structure is identical to the
Active Alarms. However, if any alarm is triggered it will
be Latched. For example, if an External Reference is
disconnected from the rear panel, an LO Fault will be
reported while the LO regains lock. After the LO
recovers, even though the Active Alarm no longer
reports the alarm, the Latched Alarm will still display
. In other words, the alarm was latched.
CLEAR ALARMS
(ENT = Y,CLR = N):
Pressing will clear all of the Latched Alarms
currently stored.
