ONFIGURING THE
The CSAT is a complete RF Down Converter Terminal, RF Up Converter Terminal, and
RF High Power Amplifier (HPA) in a single weather safe package. The following
paragraphs will define the meaning and use of all of the controllable parameter of the
CSAT.
3.3.1 F
REQUENCY
Both the Receiver frequency and the Transmitter frequency are user configurable. The
receiver frequency can be selected to any frequency divisible by either 1.0 MHz or 2.5
MHz in the valid Rx frequency range. The transmitter frequency can be selected to any
frequency divisible by either 1.0 MHz or 2.5 MHz in the valid Tx frequency range.
Associated Remote Command(s):
3.3.1 A
TTENUATION
Both the Receiver attenuation and the Transmitter attenuation are user configurable. The
receiver attenuation can be selected between 00.00 and 25.00 dB in 0.25 dB increments.
The transmitter attenuation can be selected between 00.00 and 25.00 dB in 0.25 dB
increments.
Associated Remote Command(s):
3.3.2 G O
AIN FFSET
Both the Receiver and the Transmitter Gain Offsets are user configurable. The Gain
Offset are only used in redundant configurations. The user can use these parameters to
adjust for gain difference between two CSAT Transceivers used in a 1:1 redundant
configuration. The offset can be selected between 0.00 and –4.00 dB in 0.25 dB
increments.
Associated Remote Command(s):
3.3.3 M M
UTE ODE
The CSAT offers two operating modes with regards to frequency changes and unit
muting. The two modes are; 'muted after frequency change' and 'unmuted after
frequency change'.
• If the Mute Mode is set to '1', the firmware will leave the IF or RF muted
following a change to either the Down Converter Frequency or Up Converter
Frequency respectively. The operator can then 'unmute' the unit using the
commands in the next section.
