"Chirp"
Rapid crest factor optimization regardless of the number of carriers.
The minimal crest factor is 3 dB. This value is obtained, if the follow-
ing prerequisites are fulfilled:
●
All carriers in the multicarrier signal are switched on.
●
All carriers have identical power.
In a configuration which differs from this, the achievable crest factor is
worse.
"Target Crest"
Optimization of the crest factor to a desired value for all carrier config-
urations.
The optimization time depends on the number of carriers and the
desired crest factor. Computation time increases only when the num-
ber of carriers exceeds 256 and the crest factor is below 4 dB. The
desired value can be entered in "Desired Crest Factor".
Note: Optimization can be canceled at any time, and the current
value being displayed at that moment is then used.

Desired Crest Factor
For optimization "Target Crest", defines the desired crest factor.
