Introduction1-2DRS4000 Receiver User and Technical Manual
[photo of DRS4000 (similarto cover photo)]
The receiver consists of a 2RU rack-mountable, digital, microwave receiver that supports four antenna inputs. All functions
can be operated from the front control panel.
The DRS4000 Receiver uses the latest Maximal Ratio
Combining (MaxRC) technology to optimize the quality of the
transmitted signal. The DRS4000 supports Coded Orthogonal
Frequency Division Multiplexing (COFDM) demodulation, Link
Modulation System (LMS-T) demodulation, MPEG decoding in
either standard definition or high definition (SD/HD), and optional
spectrum viewing, making it an excellent solution for expanding
and extending your remote capabilities.
with a corresponding increase in robustness over DVB-T. All
MRC and Link SD/HD ENG transmitters and wireless camera
systems also support LMS-T.
The DRS4000 Receiver exhibits more sensitivity, provides a
cleaner video image, and minimizes multipath effects when
compared to other microwave receivers.
The receiver operates on 100 to 260 VAC at 50 to 60 Hz. An
auto-sensing circuit detects actual line voltage.
You can readily change system parameters from the front panel
using a keypad and the control screen or by using a studiobased master controller. Frequently used settings can be saved
in one of 40 presets. A video monitor offers a display of live
video as well as an optional overlay of the RF spectrum.
In a typical DRS4000 system, each antenna is connected to a
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 Bias-T interfaces in both the converter and the
DRS4000 Receiver. The DRS4000 Receiver samples the
signal-to-noise ratio (SNR) from all antennas, constructing an
optimized signal from one or more of the signals. High quality
75-ohm coaxial cable (RG6 or RG11) should be used to connect
the receiver to the downconverters.
Figure 1-2 on page 1-4 depicts a typical configuration.
1.7Features
The DRS4000 Receiver offers the following features:
•Two or four antenna inputs (DVB-T/LMS-T)

operation as well as the highly advanced Link Modulation
System-Terrestrial (LMS-T). LMS-T employs COFDM
technology in a proprietary format that utilizes powerful LDPC
error correction codes to achieve a 30% increase in throughput
