Notes: 1. Only required for CW mode, do not configure for PRBS mode.
2. Frame Buffer content varies for different modulation schemes.
The content of the Frame Buffer has to be defined for Continuous Transmission PRBS
mode or CW mode. To measure the power spectral density (PSD) mask of the
transmitter it is recommended to use a random sequence of maximum length for the
PSDU data.
To measure CW signals it is necessary to write either 0x00 or 0xFF to each byte of the
Frame Buffer according to the given frame length. For details refer to Table 9-27 below.
