Channel Slope Adjust; Reference Frequency Adjust; External Reference Fault Logic - Comtech EF Data CSAT-5060 Installation And Operation Manual

5 to 25 Watt C-Band Transceiver
System Operation
• In Manual mode, the customer adjusts the channel slope using the DSA and USA
commands defined in the next section.
Associated Remote Command(s):
6.3.8 C
HANNEL
Both the Receiver IF output and the Transmitter RF output channel slopes are user
controllable.
• The receiver channel slope can be varied for approximately 2dB of positive slope.
The parameter for controlling this is the 'Down Slope Adjust' which can be
varied from 0.0 to 1.0 in 0.1 steps. 0.0 is the default setting and also is the value
used when the channel flatness is tuned and tested in the factory. 1.0 corresponds
to approximately 2dB of positive slope.
• The transmit channel slope can be varied for approximately 2dB of positive slope.
The parameter for controlling this is the 'Up Slope Adjust' which can be varied
from 0.0 to 1.0 in 0.1 steps. 0.0 is the default setting and also is the value used
when the channel flatness is tuned and tested in the factory. 1.0 corresponds to
approximately 2dB of positive slope.
Associated Remote Command(s):
6.3.9 R
EFERENCE
A manual, fine adjustment of the internal 10MHz reference frequency is provided as a
user controllable parameter. This parameter can be varied within the range 000 to 255,
with the factory default setting at 087. Varying this parameter from 000 to 255 will result
in a change of approximately 6.5kHz and 4.0kHz at the RF and IF output ports
respectively.
Associated Remote Command(s):
6.3.10 E
XTERNAL
The CSAT allows the user to select whether or not the summary fault relay is activated if
the internal 10MHz reference loses lock with the external reference attached to
'EXTERNAL REF IN port' J4.
