Family of UHF
Transmitters for TV
At a glance
The R&S®SCx8000 family of UHF transmitters offers
compactness and cost-effectiveness unique in its
power class. Designed for professional TV broadcast networks, the R&S®SCx8000 features intelligent redundancy concepts for the exciter and the
amplifier and allows easy switchover from analog
to digital transmission. The transmitters are innovative, robust, failsafe and easy to put into operation.
This makes them ideal for use at remote sites and in
outdoor applications.
The R&S®SCx8000 transmitter family covers the analog TV
standards as well as the ATSC, ATSC Mobile DTV, DVB-T,
DVB-H and MediaFLO™ digital TV standards. The transmitters can be switched from analog to digital transmission. The R&S®SCx8000 comes with broadband precorrection data for each digital standard.
Rolling out or extending a transmitter network may require large numbers of transmitters; yet costs must be
kept to a minimum. Here, the R&S®SCx8000 proves to
be the ideal choice: It comes with the high quality that
Rohde & Schwarz stands for and offers an excellent price/
performance ratio. Follow-up costs are just as favorable:
Due to its ultracompact design, the R&S®SCx8000 reduces
infrastructure, rental and installation costs. The transmitter's high efficiency ensures low energy costs throughout
the product lifecycle.
Availability is the crucial factor for operators of trans mitter
systems. The new backup exciter redundancy concept
eliminates the need for a separate transmitter control unit.
This lowers costs and increases system availability. Each
amplifier comes with two power supplies. This ensures
high failsafety, which can be further enhanced by adding a
third, optional power supply.

Transmitters with high power density
The use of large-scale integrated (LSI) components that
combine various classic transmitter functions results in a
highly compact design. The new R&S®SX801 exciter provides signal processing and transmitter control functionality at the same time. It comes with a display on its front
panel.
The base amplifier includes the amplifier unit, an exciter
switch and a signal splitter. In systems with two amplifiers,
an expansion amplifier with an internal power combiner is
added. Both the base and the expansion amplifier come
with an integrated cooling system, each featuring two fans
for redundancy.
The individual components are combined as necessary
for the required output power and application. Due to
the large number of options, including a DVB-T/DVB-H
receiver that adds retransmitter functionality to the
R&S®SCx8000, the transmitter can be tailored to the
specific application.
Autonomous cooling concept for flexible use
The compact design and integrated cooling make it easy
to install the transmitter in a broadcast station, even into
unused spaces in crowded racks. The autonomous cooling
concept makes the transmitter ideal also for installation in
outdoor racks; Rohde & Schwarz offers various solutions
for such applications.
New redundancy concepts increase availability and
save space
To create a system that makes the most economical use of
available space, the new backup exciter redundancy concept was developed. RF source redundancy is achieved by
using only two exciters. A central control unit is not required. The program exciter serves as the RF source and the
backup exciter as the transmitter control unit. If the program exciter fails, the backup exciter automatically takes
over RF transmission in addition to providing transmitter
control functionality.
An intelligent power supply standby concept provides
power supply redundancy for the amplifier. Each amplifier contains two power supplies as standard to maintain
interruption-free transmission if one of the power supplies
fails. An optional third power supply can be used to further
enhance transmission reliability.

Special features
for operation
Significant reduction of energy costs
At an efficiency of up to 22 %, the R&S®SCx8000 features
energy costs exceptionally low for a transmitter in this
power class. This makes for extremely low cost of ownership throughout the life of the transmitter.
Precorrection for digital standards with set & go
function
The transmitter can be put into operation quickly and easily and is convenient to operate. The system amplifiers
come ready with broadband precorrection for the specific digital standard on delivery. Manual precorrection is
therefore not necessary when the transmitter is put into
operation. In the UHF range, each channel can be selected
with nominal power or power reduced by up to 6 dB. The
automatic set & go function loads the precorrection curve
required for the selected frequency and power in the background. A modulation error ratio (MER) of at least 33 dB is
thus achieved for the output stage without requiring any
time-consuming manual precorrection.
The MPEG decoder option allows digital input signals to
be fed as transport streams. These streams are converted
to analog CCVS signals in the exciter FPGA, modulated
and transmitted as analog signals. If digital transmission
is desired at a later date, switchover from analog to digital
transmission can be made easily and without any hardware modification.
Operation either hands-on or via web browser
The exciter has a backlit graphical display and a keypad on
the front panel for hands-on operation. Shortcuts enable
quick access to frequently used menu items. The operating parameters are indicated by LEDs and displayed in the
overview menu.
The R&S®SCx8000 can also be operated locally or remotely
from a PC running a standard web browser. In addition,
the transmitter can be remotely monitored via an optional
SNMP agent.
In broadcasting networks containing a large number of
devices, efficient and reliable configuration management is
important. Like all modern equipment, the R&S®SCx8000
transmitters can be configured via the Internet from a
central station. In this way, device and system settings can
also be easily saved and transferred from one transmitter
to another.
Solutions for migrating from analog to digital TV
The transmitters offer intelligent concepts for network operators planning migration from analog to digital transmission. If both analog and digital signals are fed, the desired
input mode and standard can be menu-selected.
Excellent sound level
The R&S®SCx8000 stands out for exceptionally silent
operation. Its sound level is typically below 60 dBA,
depending on the configuration.

"Everything from a single source" means utmost
quality from Rohde & Schwarz
At Rohde & Schwarz, the entire value added chain lies
in one hand. This is the ideal prerequisite for long-term,
trouble-free operation of transmitter systems, since
Rohde & Schwarz products meet the most stringent
quality requirements. The transmitters were developed
with market requirements in mind right from the start.
Rohde & Schwarz manufactures its products at its own
plants. This ensures short-term, reliable product delivery
independently of external suppliers. An extensive T & M
product portfolio and worldwide service and support
round out the benefits that come with the R&S®SCx8000
family of transmitters – true to the motto: "Everything from
a single source".
Additional transmitter redundancy concepts
In addition to the innovative backup exciter concept,
Rohde & Schwarz will continue to offer the established
solutions featuring the R&S®NetCCU®800 as the central
control unit for dual drive, 1+1 and N+1 standby configurations, which provide additional features in particular with
respect to operating ease.
Self-monitoring power output stages
As is customary for Rohde & Schwarz, all power amplifiers
of the R&S®SCx8000 family of transmitters are equipped
with protective circuits. This prevents the transmitters and
their transistors from being damaged by overtemperature
or high reflected powers.
Optimal power supply design
The use of high-quality single-phase wide-range power
supplies allows the transmitter to be operated on all conventional single-phase voltages. Voltage fluctuations
can thus be compensated, eliminating the need for extra
transformers. The power supplies are able to buffer power
interruptions up to 10 ms.
