Power Reference
Defines the way the individual carriers in a composed multi carrier signal are leveled.
The difference between the provided modes is especially important if signals with dif-
ferent crest factors are composed together into a multi carrier signal.

Carrier Table
Calls the table for configuring individual carriers. A selectable carrier range can be set
with the aid of the optional "Carrier Table Assistant" (see
on page 111).
The multi carrier configuration can be checked with the aid of the "Carrier Graph".
Output settings
The "Output Settings" section in the multi carrier dialog indicates the name, the size
and the clock rate of the currently calculated multi carrier output file.

has to be calculated can be entered.

The individual carriers are leveled based on their RMS power and the
configured "Carrier Gain".
Example:
A multi carrier signal is composed from two waveform files.
First carrier "Gain" = 0 dB
Second carrier "Gain" = -3 dB
In the resulting multi carrier signal, the RMS power of the second car-
rier signal is 3 dB lower than the RMS power of the first carrier signal.
The individual carriers are leveled based on their peak power and the
configured "Carrier Gain".
Example:
A multi carrier signal is composed from two waveform files.
First carrier "Gain" = 0 dB
Second carrier "Gain" = -3 dB
In the resulting multi carrier signal, the peak power of the second car-
rier signal is 3 dB lower than the peak power of the first carrier signal.
