Lna Current Source; Lna Fault Logic - Comtech EF Data CSAT-5060 Installation And Operation Manual

CSAT-5060 50 Watt C-Band Transceiver
System Operation
3.3.13 LNA C
URRENT
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.
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
Exercise care when directly connecting the CSAT 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).
IMPORTANT
Associated Remote Command(s):
Example(s):
3.3.14 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):
Example(s):
3.3.15 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)
