SFC1800A Synthesized Frequency Upconverter User Interfaces
TM111 – Rev. 1.0 4-7
HOTSTBY STATE: {NONE, PRIME1 - 8}
Displays the number of the unit that is currently in Hot
Standby. Hot Standby is only active when the switch
Mode is set to Auto (Revertive or Nonrevertive). In this
condition, the Prime Converter with the highest assigned
priority is put in Hot Standby.
PRIME #:
SUMMARY FAULT: {PASS, FAIL}
Reports the system fault status. This is the summary of
all the Major, Minor, and Common Alarms currently
present in all the individual Prime Converters.
LEARNED: {YES, NO}
Reports whether the Prime has been learned by the
Backup.
BACKUP TEST: {PASS, FAIL}
Reports whether the Prime has passed the Backup Test.
CONFIG CHANGED: {YES, NO}
Reports whether the Prime configuration has changed
since being learned by the Backup.
RELAY STATUS: {ON, OFF}
Displays the status of the Prime Unit's corresponding RF
Relay in the switch Unit. 'On' indicates that the Prime is
being backed up.
4.2.4 Monitor Menu Options and Parameters
REFERENCE:
{INTERNAL, EXTERNAL}
Indicates the reference source of the unit. The
SFC1800A Upconverter will detect a valid external
reference source when it is connected to J4 on the rear
panel and automatically select 'External'. Likewise,
when no signal (or a signal not meeting the Reference
input specification) is connected to J4, the unit will switch
to the 'Internal'. The process is completely automatic,
and it is independent of M&C control.
MON VOLTAGES:
RF DETECTOR V: Monitors the voltage of the RF Detector.
IF DETECTOR V: Monitors the voltage of the IF Detector.
DAC ATTEN V: Monitors the voltage of the Output Attenuator DAC.
VCC1 VOLTAGE: Displays the voltage of the Controller PCB
Microprocessor +5V.
+9V VOLTAGE: Displays the voltage of the System Supply +9V.
