DR3

The DR3 is a third generation diversity receiver incorporating all the best features of Nucomm's popular DR1 and DR2, along with a host of exciting new features that set it apart from any other receivers on the market.

Product Features

  • 6 way maximum-ratio combining (MaxRC)
  • High-dynamic-range block down converters
  • Variable bandwidth COFDM - 1.25 to 8 MHz
  • Pre-select bandpass filters for high selectivity
  • Built-in spectrum analyzer displayed on front panel
  • HDMI monitor output with spectrum OSD overlay
  • High adjacent channel selectivity >40 dB
  • User control via capacitive touch-screen

Digital COFDM IP Diversity HD/SD Receiver

The DR3 receiver is configured with six diversity COFDM demodulators using maximum-ratio combining (MRC), which significantly improves the robustness of higher data rate COFDM modulation. Spatial diversity increases system perfor-mance 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.

The DR3 is available the bandwidths of 1.25, 2.5, 6, 7 and 8MHz allowing for 1 to 31 Mbps data rates. The DR3 receiver is configured with an internal low-latency multi-format H.264/MPEG2 HD/SD monitoring decoder. A DVB-ASI output is available that can be fed to an external decoder. The control panel uses a capacitive touchscreen that provides easy navigation through the menu system. Remote control is facilitated via Ethernet.
