LNA Fault Logic: Summary
No-Summary
The user is prompted to select either Summary or No Summary, using the ◄ ► arrow
keys, then to press ENT. This controls whether or not a LNA Current-Window fault will
activate the SUMMARY FAULT RELAY. This allows the user to select whether or not
to switch the ONLINE/OFFLINE CSAT in the event of a LNA current-window fault.

ExternalRef Fault Logic:
Summary No-Summary
The user is prompted to select either Summary or No-Summary, using the ◄ ► arrow
keys, then to press ENT. NOTE: The CSAT will automatically lock 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 is activated if the CSAT loses lock with the
external reference.

Internal Ref Adjustment:
087
The user is prompted to edit the Internal 10MHz Reference setting using the ▲ ▼ arrow
keys, then to press ENT. The value will scroll between 000 and 255. NOTE: The
Internal Reference is adjusted in the factory to be very accurate with the default setting of
087. This parameter is made available to compensate for the long-term frequency drift of
the oscillator.
