Figure 5-27 illustrates the minimal spectral occupation
achievable in the European band, ensure that the min-
imum frequency deviation that a MRF89XA receiver
can accept is 33 kHz. If the companion receiver can
accept smaller frequency deviations, the range of mod-
ulation bandwidth can be further decreased.
FIGURE 5-27:
The default configuration of the MRF89XA yields the
bandwidth visible on Figure 5-28.
