Calculator.
Note:This field is provided

for convenience purposes
only and to aid in the

automatic calculation of the
Modulator frequency. The

actual setting will depend
on your external hardware

(Block Upconverter), and
may differ from the value

set in here.

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.

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

Short
Normal
