Attribute Meaning
Lower Center
Frequency
Not displayed when Spectrum Management Control is set to
‘Fixed Frequency’. The software allows a user to optionally
adjust the channel center frequencies. Changing the Lower
Center Frequency attribute causes all channel center
frequencies to be offset. It effectively slides the
channelization up or down.
CAUTION
The lower center frequency attribute must be configured
to the same value for both the master and slave. Failure
to do so will cause the wireless link to fail
reestablishment. The only way to recover from this
situation is to modify the Lower Center Frequency
attribute so that they are identical on both the master
and slave unit.
Default Raster This is only displayed when Spectrum Management Control is
set to ‘Fixed Frequency’. If this is set to ‘On’, the list of
options presented in the fixed Tx frequency box is limited by
the default raster.
