[:SOURce<hw>]:BB:T2DVb:PLP<ch>:CONStel
Const. Rotation
Editing the parameter requires "T2-MI Interface > Off".
Sets the constellation rotation state.
"On"
Transmits the constellation rotated, i.e. the Q path is delayed vs. the I
path. For each constellation, there is a different (but fixed) angle of
rotation.
"Off"
Transmits non-rotated constellation.
Remote command:

Time Interleaver Type
Editing the parameter requires "T2-MI Interface > Off".
Defines the time interleaver type.
"0"
Maps each interleaving frame directly to a T2
frame.
"1"
Maps each interleaving frame to more than one T2
frame.
Remote command:
[:SOURce<hw>]:BB:T2DVb:PLP<ch>:TIL:TYPE
Frame Interval (I
Jump
)
Defines the time interleaver frame interval (I
Jump
).
"1"
Used if the PLP appears in each frame. Fixed setting for single PLP.
"2" to "255"
Requires a multi-PLP setup.
If frame interval is 2, for example, an interleaving frame is distributed
among two successive T2
frames with an even frame index. For limi-
.
Remote command:
[:SOURce<hw>]:BB:T2DVb:PLP<ch>:TIL:FINT
Time Interleaver Length
Defines the time interleaver length within the time interleaving frame.
If a length of "0" is set and if "Time Interleaver Type"
=
"0", time interleaving is disabled.
Remote command:
[:SOURce<hw>]:BB:T2DVb:PLP<ch>:TIL:LENGth
First Frame Index
Displays the index of the first frame of the super frame, in that the current PLP occurs.
