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):

DGO= -1.75, UGO=1.00

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.

• If the Mute Mode is set to ‘0’, the firmware will automatically ‘unmute’

the IF or RF following a change to the Down Converter Frequency or Up
Converter Frequency respectively. This assumes that the unit was
‘unmuted’ prior to the frequency change and that there are no faults
following the change. The factory default for this mode is ‘1’.

Associated Remote Command(s):

The output state of both the Receiver and the Transmitter are user controllable.
The receiver output state (the ‘IF IN’ port, J1) will be ON only if the following
two requirements are met:

(1) The receiver hardware must be fault free

(i.e. No Synthesiser or IFLO faults).

(2) The receiver must be unmuted (i.e. DMU=0 ).
