The length
Δ
is expressed in fractions of the active OFDM symbol duration T
U
, e.g.
Δ
/

19/256
Note:
Not all possible combinations of the guard interval with the following parameters are
allowed:

Remote command:
[:SOURce<hw>]:BB:T2DVb:GUARd:INTerval
Pilot Pattern
Editing the parameter requires "T2-MI Interface > Off".
Sets the pilot pattern.
You can select pattern "PP1" to "PP8".

Remote command:
T2 Frames per Super Frame (N_T2)
Editing the parameter requires "T2-MI Interface > Off".
Sets the number of T2
frames per super frame.
Remote command:
[:SOURce<hw>]:BB:T2DVb:NT2Frames
OFDM Symbols per T2 Frame (L_F)
Displays the computed number of OFDM symbols per T2
frame L
F
.
L
F
equals the sum of number of data symbols per T2
frame L
Data
plus the number of
P2
symbols L
P2
:
L
F
=
L
Data
+
L
P2
The sum constitutes the number of P2 symbols and the data symbols without the
P1
symbol. The number of P2
symbols in a T2
frame depends on the "FFT Size".
Remote command:
Data Symbols per T2 Frame (L_DATA)
Editing the parameter requires "T2-MI Interface > Off".
Sets the number of data symbols per T2
frame.
L
Data
equals the difference of number of OFDM symbols per T2
frame L
F
minus the
number of P2
symbols L
P2
:
