1.1 Outline
Chapter 1 Introduction
FUTV3506 DVB-T2 modulator is our new product developed complying with the
DVB-T2 standard. With its advanced modulating technology, this modulator can
effectively make use of the ground spectrum resources and make it possible to
provide reliable signals for fixed, mobile and portable devices. Compared with
DVB-T, the channel capacity is increased by 30% under the similar carrier to
noise ratio (CNR) threshold. FUTV3506 DVB-T2 modulator also supports
single-PLP and can receive transmission data and synchronous information from
DVB-T2 Gateway through its ASI and IP ports.
Moreover, this device can be upgraded and controlled through network system,
which allows it to be widely used in setting up digital broadcasting network and
provide good signals for scientific laboratory and DVB-T2 STB.

The range is determined conjointly by FFT size and Guard Interval.
If you set an inappropriate value (lower the minimum value or higher than the
maximum value), it can automatically cast it to a proper value. To be specific, if you
input a value lower than the minimum value allowed, the system will cast it to the
minimum value. Similarly, the system will cast it to the maximum value allowed if
you put an over-high value.

Ø Rotation
Users can set the constellation rotation at this menu.
2.5.5 Rotation 1/1
[Off] On
When constellation rotation is used, the normalized cell values of each FEC block
coming from the constellation mapper are rotated in the complex plane and the
imaginary part cyclically delayed by one cell within a FEC block.
When constellation rotation is not used, the cells are passed onto the cell interleave
unmodified.
Ø Time IL Length
Users can set the time interleaving length at this menu. An inappropriate value will be
automatically and compulsorily corrected to adapt the settings.
The time interleave will typically act as a buffer for PLP data and therefore the output
may be delayed by a varying amount with respect to the input even when time
interleaving is not used.
If time interleaving is not used, set the Time IL Length=0.
2.5.6 Time IL Length
