on page 112
FEF Length ← Future Extension Frames
Displays the length of the associated FEF part as the number of elementary periods T.
The length is measured from the start of the P1 symbol of the FEF part to the start of
the P1 symbol of the next T2
frame.
Remote command:
[:SOURce<hw>]:BB:T2DVb:FEF:LENGth
on page 111
FEF Interval ← Future Extension Frames
Displays the number of T2 frames between two FEF parts. The specification ETSI EN
302 755 states, that the T2 frame is the first frame in a T2 super frame which contains
both FEF parts and T2 frames.

FEF Payload ← Future Extension Frames
Sets the FEF payload.
"Null" I/Q values of the FEF payload are set to zero.
"Noise" I/Q values of the FEF payload are modulated in the frequency domain
using a PRBS and transformed into the time domain by
IFFT .
The technique allows generating payload with a power level equal to
the T2 frame.
