Selection Setting
Fault-Logic:
Summary or No-Summary . This controls whether or not an LNA Current-
Window fault activates the Summary Fault Relay, and further permits you to
select whether or not to switch the Online/Offline CSAT in the event of an LNA
Current-Window fault.
Press ENTER when done.

Selection Setting
Cold-Start If enabled, when the CSAT is powered on, the IF and RF outputs remain muted for 15
minutes.
AFR
(Auto Fault Recovery) This defines how a CSAT reacts to momentary fault conditions:
Off: CSAT mutes when faulted and remain muted.
On: CSAT mutes when faulted, but unmute after the fault goes away.
Xref (External Reference) The CSAT automatically locks to an external 5 or 10 MHz
reference independent of the state of this selection. This selection determines whether
or not the Summary Fault Relay activates if the CSAT loses lock with the external
reference.
Ref-Adj Select a value for the Internal 10MHz Reference setting from 000 to 255 .
NOTE: The Internal Reference is set in the factory to be very accurate with the default
setting of 087. This setting is provided to compensate for the long-term frequency drift
of the oscillator.
Sync-Clk (Default is NO .) Selecting YES and pressing ENTER causes the CSAT RTC (Real-
Time Clock) to be synchronized to the Modem RTC.
