1.6 Typical Application of Dual Carrier Outputs
As we all know, to guarantee the picture quality of 1920x1080@50I/60I resolution HD

program, the video bit-rate may exceed 10Mbps, even up to 15Mbps. However, the
maximum possible bit-rate output for single DVB-T carrier is only around 30Mbps.
15Mbps x4 =60Mbps > 30Mbps.
It means the single DVB-T carrier simply can't carry the 4 channels 1080i HD
programs if the average bit-rate reaches 15Mbps.
That's why we design 2*DVB-T carrier modulation board which double the maximum
possible bit-rate bandwidth up to 60Mbps, which rightly makes it reliably carry 4
channels HD programs output simultaneously.
Below brief chart will help to more clearly illustrate the working principle.

Requiring device power, air-conditioning power and lighting
power are independent to each other. Device power requires
AC 110V±10%, 50/60Hz or AC 220V±10%, 50/60Hz. Please
carefully check before running.
2.5 Grounding Requirement
All function modules’ good grounding is the basis of reliability and stability of devices.
Also, they are the most important guarantee of lightning arresting and interference
rejection. Therefore, the system must follow this rule.
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.
Users should make sure the 2 ends of grounding wire well electric conducted and be
antirust.
It is prohibited to use any other device as part of grounding electric circuit

The area of the conduction between grounding wire and device’s frame should be no
less than 25 mm2.

Carrier A (or B). Move the triangle mark to specify the program and press
RIGHT/LEFT keys to shift the mark between “√” and “X”. (“√”: to output the
corresponding program; “X”: not to output the corresponding program)
3) Modulator Setting
When entering “Modulator Setting” submenu, user can find below different
parameters can be set and the LCD window would show as below:
As the NDS3542A is with dual carrier outputs, “3.1” and “3.2” represent the
“Carrier A” and “Carrier B” respectively. User can enter “3.1” or “3.2” to set the
corresponding modulating parameters. Submenus are as below:
Bandwidth
There are three possible options provided for selecting bandwidth: 6M, 7M, and 8M.
When the display shows them, user just need swift LEFT and RIGHT key to choose

There are three different constellations QPSK, 16QAM and 64QAM shown on the LCD
window. When entering Constellation, user can apply the same setting method as
mentioned above to select and confirm one mode.
Transmission Mode
When user enters Transmission Mode, the LCD would show the current working mode.
User can move LEFT/RIGHT keys to select and press ENTER key to confirm. 2K and
8K are the options:
2K: When the device works as current mode, the number of current carrier is 2048
8K: When the device works as current mode, the number of current carrier is 8192
Guard Interval
In communications, guard intervals are used to ensure that distant transmissions do
not interfere with each other. These transmissions may belong to different users (as in
TDMA) or same user (as in OFDM). The purpose of the guard interval is to
introduce immunity to propagation delays, echoes and reflections, to which digital
data is normally very sensitive. There are four possible options provided to be
selected. They are 1/4, 1/8, 1/16, 1/32. User can shift the LEFT/RIGHT keys to select
and press ENTER to confirm.
