The Tx amplifier ON/OFF state is user controllable. Turning the Tx amplifier OFF
removes the 10Vdc supply to the RF Power FETs. The TX Amplifier must be ON in
order for the CSAT to transmit a RF signal.

Comtech EF Data’s CSAT transcievers provide two operating modes for the Receiver IF
and Transmitter RF output channel slopes; ‘Calibrated’ and ‘Manual’ modes.
• In Calibrated mode, the CSAT firmware uses a calibration ‘lookup’ table based
on the selected frequency to determine the optimum channel slope setting.
• In Manual mode, the customer adjusts the channel slope using the DSA and USA
commands defined in the next section.
Associated Remote Command(s): DSM=, USM=

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.
