Note:
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 recom-
mended 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 the Frame Buffer, for
details refer to
Table 20-2.
