PLP Constellation
Rotation
It shows if the constellation is rotated (ON) or not (OFF).
PLP ID:
It is the PLP identifier. When PLP mode is single, it identifies the
input stream (0-255). When PLP mode is multiple, the user can
select the PLP ID to see.
PLP Code Rate:
It defines the ratio between the data bits number and the total
number of bits transmitted (the difference corresponds to the number
of control bits for the error detection and recovery): 1/2, 3/5, 2/3, 3/4,
4/5, 5/6.
Cell ID, Network ID and T2 System ID parameters are defined in accordance with
the DVB standard.

signals parameters which can be defined by user and are described below:
1)
Channel BW (channel bandwidth)
Enables the channel bandwidth to be selected over a range from 1.3 MHz to
60.75 MHz. The selection of this parameter is essential for the correct operation of
the tuner, as it affects the frequency separation of the carriers. If you change the
bandwidth the Symbol Rate changes proportionally and vice versa.
2)
Spectral Inv
If necessary, activate the Spectral inversion (On). Reception will be bad if
spectral inversion has been incorrectly selected.
