4.2.11 Cold Start Function
The CSAT provides an optional ‘Cold Start’ feature that will ensure that the
internal 10MHz reference signal is at a stable temperature prior to allowing the
RF and IF outputs to be turned ON. A fixed cold start interval of 15 minutes is
used.
• If ‘Cold Start’ is ON when the CSAT is powered ON, the IF and RF
outputs will remain muted for 15 minutes even if all the conditions
defined in 3.3.4 are satisfied. At the end of the 15-minute interval, the
RF and IF output will automatically be turned ON if the conditions of
3.3.4 are met.
• If a CSAT was powered ON with ‘Cold Start ON’, the operator can
override this function by setting ‘Cold Start OFF’.

4.2.12 Auto Fault Recovery
This parameter defines how the CSAT responds to momentary fault conditions.
• If ‘Auto Fault Recovery‘ is OFF and a fault condition occurs, that
causes either the RF or IF output to be muted, then that fault condition
clears, the CSAT will remain muted. In this mode, operator
intervention is necessary to return the CSAT to normal operating
mode.
•
If ‘Auto Fault Recovery’ is ON and the same situation occurs, the
CSAT will automatically be unmuted and return to normal operating
mode. To protect against repetitive, momentary faults, if the CSAT
experiences five occurrences of the same fault, the ‘Auto Fault
Recovery’ parameter will automatically be set to OFF
.
Example: If the Upconverter IFLO synthesizer goes unlocked and starts
sweeping while Auto Fault Recovery is ON, the CSAT would see a
unlocked / locked condition at the sweep rate of the IFLO synthesizer.
After the 5th occurrence, the firmware will set Auto Fault Recovery to
OFF and keep the CSAT RF output muted.
