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.

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 Up Converter 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.
