Alternatively, this value may be set to 0 to
disable auto-calculation.
Uplink
Frequency
This field should contain the frequency of
the satellite uplink paperwork.
It is provided for convenience purposes
only and to aid in the automatic
calculation of the Modulator frequency.
Always verify other Frequency settings.
This field may only be changed
if Tx is DISABLED.
Frequency Allows the operator to enter the desired
output frequency of the main RF output
port.
7039: 950MHz - 1.75GHz
LBAND
7139: 950MHz - 2.15GHz
LBAND
50MHz - 180MHz IF
** The monitor output
frequency for the EN-XX IF is
fixed at 1.080GHz. The monitor
output frequency for the EN-XX
L-Band tracks with the main RF
output frequency. This field
may only be changed if Tx is
DISABLED.
Power Allows the operator to configure the
output power of the main RF output port.
The monitor output power level for the
EN-XX IF and L-Band is fixed at -45dBm.
Power is defined as the composite power
referenced to an un-modulated (Pure
Carrier) carrier.
7039: -50 to -7dBm LBAND
7139: -35 to +5dBm LBAND
-30 to +5dBm IF
Spectrum
Inversion
The Spectrum Inversion options are either
Normal or Invert. If Normal is selected,
then spectrum inversion does not occur.
Spectral inversion can occur when either
the baseband signal is up-converted to an
IF frequency or when the IF is
upconverted to the desired RF output
frequency.
Invert
Normal
FEC Frame When operating in DVB-S2, the Frame
Type options are either Normal or Short.
The Normal 64,800-bit FEC frame
provides better protection but introduces
more latency compared to the Short
16,200-bit FEC frame. Therefore, the
Short FEC frame type should be selected
in applications where latency is critical and
the longer frame type should be used to
Short
Normal
