1.6 System Description

The DRS2000HS/DRS6000HS Digital Diversity Receiver (Figure

1-1) is a high performance, cost-effective COFDM receiver suit-

able for public safety, government, and homeland security opera-

tions. The receiver is an ideal choice for applications that require

hands-off antenna diversity.

Figure 1-1 DRS2000HS/DRS6000HS Receiver - Typical

The receiver consists of a 2RU high, rack-mountable, digital

microwave receiver that supports either two or six antenna

inputs. All functions can be operated from the front control

panel.

The receiver uses the latest maximal ratio combining (MaxRC)

technology to optimize the quality of the transmitted signal. The

receiver supports Coded Orthogonal Frequency Division

Multiplexing (COFDM) demodulation, and MPEG decoding in

standard definition (SD).

The receiver operates on 100 to 260 VAC at 50 to 60 Hz. An

auto-sensing circuit detects actual line voltage.

You can readily monitor current settings with the front control

panel or change system parameters using the keypad and the

control panel. Frequently used settings can be saved in one of

50 presets. A video monitor offers a display of live video.

Introduction 1-3DRS2000HS/DRS6000HS User and Technical Manual

In a typical system, each antenna is connected to a separate

low-noise block downconverter (BDC) by a short cable or direct

N-Type connector. The converters output a UHF signal through

coaxial cable to UHF input ports at the rear of the receiver. The

receiver and downconverters may be separated by up to 600

feet (183 m), depending on frequency and cable type.

Incoming signals and downconverter power travel on the same

cable using BiasT interfaces in both the converter and the

receiver. The receiver samples the signal-to-noise ratio (SNR)

from all antennas, constructing an optimized signal from one or

more signals. High quality RG-6 or RG-11, 75-ohm coaxial cable

should be used to connect the receiver and downconverters.

The COFDM demodulator and SD MPEG decoder support

standard Digital Video Broadcast-Terrestrial (DVB-T) 2K

operation.

A typical configuration is shown in Figure 1-2 on page 1-4.

1.7 Features

The receiver offers the following features:

• Two antenna inputs (DVB-T, DRS2000HS Receiver only)

• Up to six antenna inputs (DVB-T, DRS6000HS Receiver

only)

• Maximal ratio combining (MaxRC) diversity technology

• Supports DVB-T demodulation technology

• Front panel live video monitor

• Real-time front panel monitoring for Signal-to-Noise

(SNR), Link Quality signal integrity (LQ), Receive Carrier

Level (RCL), and Bit Error Rate (BER)

• Embedded real-time operating system accessible via

front panel control screen

• Up to 50 programmable presets (saved settings) using the

receiver control panel

• Rack Mountable, compact EIA 19-inch rack, 2 RU height

• Supports 6, 7, and 8 MHz COFDM/DVB-T pedestals

• Internal web server for remote management via a

networked computer

• Band plans can be customized

• Compatible with MRC and Link Research low-noise block

downconverters. See “Block Downconverter Options” on

page 1-6 for options.

1.8 Hardware Components

A typical installation consists of a receiver, low-noise block

downconverters, filters, antennas, and cables.

1.8.1 Receiver

The DRS2000HS accepts 2 antenna inputs and the DRS6000HS

accepts 6 antenna inputs. Both receivers incorporate MaxRC

diversity technology, COFDM demodulation, SD MPEG

decoding, and DVB-T demodulation mode. With a front panel

video monitor and control screen, the receiver takes up only 2

RU of space in a 19-inch rack. The receiver can be operated

locally or remotely via a master controller.

The base model includes:

• 2- or 6-input receiver

• MaxRC diversity

• SD decoding.
