Rohde & Schwarz Test Solutions for
5G Base Stations
R

ohde & Schwarz has extended
its portfolio for generation and
analysis of 5G signal waveforms. For 5G
base stations, RF test solutions for the
5G frequency ranges FR1 (450 MHz to
7.125 GHz) and FR2 up to 44 GHz.
For over-the-air (OTA) tests on 5G
base stations in the FR2 range, Rohde
& Schwarz is launching a unique
solution based on the R&S FE44
frontend modules, which support
signal generation and analysis in the
lower-frequency IF band. This enables
low-loss transmission of 5G signals
and the use of cost-effective T&M
instruments by avoiding the need for
equipment designed for the millimetre
wave range. The R&S SMW200A
vector signal generator generates the
5G signals, and the R&S FSVA3000
provides the right analysis functions.
In the transmit direction, the 5G
signals generated in the IF band by
the R&S SMW200A are upconverted
to the FR2 range up to 44 GHz. This
ensures that the high output power is

generated exactly where it is needed.
On the receive side, the R&S FE44A
converts the FR2 signal at the antenna
inputs down to the IF band and sends it
with low attenuation losses to the R&S
FSVA3000 for analysis. This solution is
suitable for test systems in production.
For speed-optimised production
tests of 5G base stations, Rohde &
Schwarz has developed a scalable,
high-performance server based testing
analysis platform. The R&S SMBV100B
vector signal generator and the R&S
FSVA3000 spectrum analyser are used
as RF test solutions. The powerful R&S
QuickStep test executive software is
used to automatically control the test
setup and verify test results.
Rohde & Schwarz also offers a new
test solution for base stations and
small cells that enables cross-channel
measurements up to 4x4 MIMO on 5G
transmissions in the FR1 range. The
solution consists of the R&S SMW200A
signal generator, two R&S SGT100A
vector RF sources, the R&S RTP164

Setup for cross-channel measurements up to 4x4 MIMO on 5G transmissions

high-performance oscilloscope used
as a measuring receiver, and the 5G
analysis options of the R&S VSE vector
signal explorer software running on a
laptop.
The R&S SMW200A generates the
3GPP-compliant 5G test signals, which
can be transmitted on up to four
channels using the two additional
vector RF sources. The oscilloscope
provides phase coherent acquisition
of all four signals, a basic prerequisite

OWNZONES Connect Helps
Keep the Content Flowing
T

here's been a substantial surge
in demand for content since
COVID-19 forced the world to stay at
home. Though demand is at an alltime high, production has slowed
dramatically, and even halted for
studios and content companies.
On-prem facilities are shutting down
around the world, and companies are
having to re-evaluate their content
supply chains in order to continue to
supply fresh content to meet the surge
in demand worldwide. For many, the
only solution to keep the lights on and
catalogues stocked is the cloud.
Though the industry has been
trending towards the cloud for a few
years now, the pandemic accelerated
the move to the cloud for many
companies almost overnight. Remote
working is the new normal and
companies are evaluating how to
maintain business continuity while
their workers and vendors are globally
dispersed, finding their path forward in
the cloud.

Platforms that are cloudbased and focused on
orchestrating tasks and
workflows between vendors
are enabling production
workflows to continue
running, more efficiently
than before. OWNZONES
Connect,
the
content
servicing and supply chain
platform built in the cloud,
is that platform.
Users can access Connect
through a browser window,
so internal and external
stakeholders can access the
platform from anywhere,
anytime. Remote Connect users can
get the full processing power of a
data centre from a browser in their
living room. Connect can scale up
to 1,000 nodes in the cloud with
7,000 processors. Granular user
roles and permissions allow a team
of professionals to work in unison,
despite geographic location, while

for cross-channel measurements.
The integrated hardware-accelerated
digital downconverter of the R&S
RTP164 mixes the signals down to the
baseband in real-time. The R&S VSE
software performs measurements in
line with 3GPP specifications. Users
can also perform MIMO-specific
measurements and flexibly compile
the test results. The solution is suitable
for tests during the development and
verification of 5G base stations.

there where all relevant parties
can have access to the same files,
regardless of physical location. What's
unique
about
Connect
is that it gives content
creators/owners the keys
to control their own content
in the cloud at no extra cost
to them. Connect makes it
possible for companies to
service their entire library
of archived content from
end-to-end entirely in the
cloud.
Operating in the cloud is
of the utmost importance
today, but migrating all of
your assets and workflows
is something that's often
seen as a significant hurdle
OWNZONES Connect deep analysis to companies with large
companies can rest assured that libraries. To help content creators
their content is secure. Being able to get their content into the cloud, and
access and monetise archive content into living rooms worldwide, we
has become increasingly important are offering free support to rapidly

The cloud is instrumental in affording and get them working in the cloud.
