• If a CSAT was powered ON with ‘Cold Start ON’, the operator can

override this function by setting ‘Cold Start OFF’.

ECOVERY

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.

OURCE

The CSAT has the circuitry necessary to source current, at 11 Vdc, up the ‘RF IN
port’ J7, to power a LNA. This current source can be turned ON/OFF via the user.
This source is capable of providing up to 400 mA.

WARNING

Never turn the unit ON without proper waveguide termination on the J2 “RF
OUTPUT” port. Individuals can be exposed to dangerously high electromagnetic
levels.

IMPORTANT

Exercise care when directly connecting the XSAT to Laboratory Test Equipment.
A DC block should be used between the J7 “RF IN”’ port and RF test source to
protect the test equipment in case the source is accidentally turned ON. (The
factory default is OFF).
