Product Code: NewscasterDR2Nucomm |
The Newscaster DR2 is a split box
HD/SD COFDM diversity microwave receiver intended for outside
broadcast and other mobile video applications. Its stylish
rugged machined housing provides durability and excellent
thermal characteristics for operation in the harshest of
conditions. The receiver has four RF inputs that communicate
directly with the system's external intelligent receivers in
1.99 to 2.70 GHz and 6.40 to 7.75 GHz. Other bands are
available. The use of external intelligent receivers allows the
receive antennas to be remotely mounted.
The DR2 receiver can be configured with dual or quad diversity
demodulators using maximum ratio combining, which significantly
improves the robustness of higher data rate COFDM modulation.
Spatial diversity increases system performance by digitally
combining signals with different characteristics. This
essentially fills in the gaps in the channel and provides
improved path reliability. The built in spectrum analyzer gives
an instant analysis of the selected channel and can be used to
minimize multi-path or see if the channel is clear from
interference, individual antennas can be switched off as
required to maximize link reliability. |
