Comtech EF Data CSAT-5060 Installation And Operation Manual page 63

100Watt C-Band Transceiver
System Operation
3.3.12 LNA C
URRENT
The CSAT has the circuitry necessary to source current, at 12 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.
Never turn the unit ON without proper waveguide termination on the
J2 "RF OUTPUT" port. Individuals can be exposed to dangerously
high electromagnetic levels.
WARNING
Excersise care when directly connecting the CSAT to Laboratory Test Equipment, a DC
block should be used between the J2 '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).
Associated Remote Command(s):
3.3.13 LNA C
URRENT
The CSAT provides the capability to monitor the LNA current when configured to supply
current to a LNA. In addition, an adjustable window detect for the LNA current is
provided. After attaching the LNA and turning on the current source, the user can
'Calibrate' the current and set a window from ±20% to ±50% to trigger an alarm. The
user can disable the 'window detect' feature by setting the window value to ±99%. (The
factory default is 99)
Associated Remote Command(s):
3.3.14 LNA F
AULT
The CSAT allows the user to select whether or not the summary fault relay is activated if
the LNA current moves out the prescribed window. This allows the user to control
whether or not the redundancy controller will switch on a LNA current alarm in the
redundant configuration. (The factory default is 0)
