Chapter 1 Product Outline
1.1 Outlines
FUTV4440B 4 in 1 QAM is a cost effective integrated QAM
modulator newly designed by FMUSER Company. This device is
integrated up to 4 channel QAM modulating carrier outputs, in
which each carrier has independent signal channel encoding
and direct RF output. Therefore, the device is featured with
excellent RF performance index. It supports 4 channel ASI
inputs (4 QAM (J.83 A/B/C), 4 DVB-S tuner input or 4 DVB-S2
tuner input). Alternatively, this device can take various RF inputs
of DVB-S/DVB-C/DVB-S2 signals by installing the relevant
build-in tuners. Hence, one PCS 4 in 1 QAM modulator can work
as 4 standalone QAM modulators, significantly reducing the

local and remote control to set its working parameters.

important guarantee of lightning arresting and interference
rejection. Therefore, system must follow this rule:
1. Coaxial cable’s outer conductor and isolation layer should
keep sound electric conducting with the metal housing of device.
2. Grounding conductor must adopt copper conductor in order to
reduce high frequency impedance, and the grounding wire must
be as thick and short as possible.
3. The 2 terminals of grounding wire must make sure for well
electric conducting, and process for antirust.
4. It is prohibited that users use other devices as part of
grounding wire’s electric circuit

4.2.2.2 Modulate Mode
Press “Modulate Mode” to enter the interface to select one
modulate standard according to the content displayed. As the
FUTV4440B modulator supports J.83A/DVB-C, J.83B, and
J.83C standard, the display shows as below:
4.2.2.3 Constellation
Press “Constellation” to enter the QAM modulation mode
selection, ENTER to the specified setting. The display shows as
below:
There possible options are different according to the different
modulate standard set in 1.2. (J.83A/DVB-C: 16QAM, 32QAM,
64QAM, 128QAM and 256QAM; J.83B: 64QAM and 256QAM;
J.83C: 64QAM and 256QAM). User can press ENTER and move
UP/DOWN key to choose the constellation as needed, and then
repress ENETER after modification to confirm.
Note: The more advanced QAM constellation mode, the higher
transmission efficiency and TS coding rate which the device can

transport at the same symbol rate. Accordingly, with the TS
coding rate increasing, the signals’ anti-jamming capability will
become weaker. Hence, those wired network currently in effect
usually adopt QAM modulation mode no exceeding 64QAM.
What needs to be pointed out is, the effective coding rate this
modulator can transport is limitary when the device works as
different constellations and symbol rates.
User can refer to the formula as below:
Max_input_bitrate = Symb_rate*qam_bits*188/204
Max input bit rate: the maximum effective inputting coding rate
Symb rate: the symbol rate
Qam_bits: the QAM bit when device works as current
constellation (user can refer to the following table when device
works as 6.875Msps symbol rate):

4.2.2.4 Symbol Rate
After entering the submenu by pressing ENTER key, user can
set the symbol rate by moving the UP/DOWN/LEFT/RIGHT key
and then repressing ENTER to confirm.
The symbol rate range is from 5.0~7.0 Msps in 1ksps step.
Note: When users choose 6M as the frequency point bandwidth,
the symbol rate should not exceed 5.217Msps;
When users choose 8M as the frequency point bandwidth, the
symbol rate should not exceed 6.956Msps.
4.2.2.5 Bandwidth
After entering the submenu by pressing ENTER key, user can
set the bandwidth by moving the LEFT/RIGHT key and then
repressing ENTER to confirm.
There are two possible options: 6MHz and 8MHz.
