The SR5500 provides extremely realistic yet repeatable
emulation of RF channel conditions for testing modern wireless
receivers. The emulator replicates real-world fading, spatial
channel conditions, MIMO and SISO channels, Additive White
Gaussian Noise (AWGN) and much more, making it possible
to isolate performance issues early in the development and
design verification cycle. The SR5500 is the most flexible
channel emulator ever offered. It can be tailored to fit today’s
requirements and budgetary business cases, yet its futureproofed modular architecture ensures that it will be ready to meet
your needs in years to come.

SPIRENT WIRELESS CHANNEL EMULATOR
SR5500 Wireless Channel Emulator
Today’s wireless industry faces many uncertainties, including a
quickly-evolving technology front. Responsible test plans require
efficient, customizable integrated solutions that can address both
current and future needs without incurring unnecessary risks. To
accelerate time to market without forgoing accuracy, Spirent’s
unique real-world emulation continues to be the first choice in
test plans.

MAXIMIZING THE RETURN ON YOUR TEST
EQUIPMENT INVESTMENT
The SR5500 system can be purchased as a system solution
or a fully modular solution. The only difference is that the
modular version allows each SR5500 module to be run under
its own GUI. While each module can be run independently in
either case, the modular solution allows any module or set of
modules to run under a separate GUI.
The integrated system solution
The SR5500 system solution makes use of one primary unit
and one or more secondary modules. Unlike pre-racked
fading “systems”, each module can be either independently
controlled or used as part of a synchronized MIMO/bidirectional channel emulation solution. And unlike other
monolithic faders, the SR5500 System Solution can be
upgraded if you need each module to have the “brains” to
interface with a separate GUI… for occasional use in separate
labs, for example. Spirent’s System Solution eliminates the risk
that the fading solution you choose today might be obsolete
tomorrow.
Spirent SR5500 system solutions are the perfect answer when
you require the best in professional fading and RF emulation
today, and your test benches are co-located so they can
connect to a single Ethernet interface. For owners of existing
SR5500 Wireless Channel Emulators, the system solution also
provides a budget-friendly upgrade to higher-order MIMO or
bi-directional testing. Best of all when your needs expand,
secondary modules can easily be upgraded to full stand-alone
capability.
The modular S
R5500 solution
Sometimes you need the flexibility to test with multiple systems,
each with fewer channels, but located in separate labs. The
exclusive modular architecture of the SR5500 makes sure that
you can concentrate fading power when you need it, but reconfigure as quickly and as often as you need to.
For example, one day you might need a completely synchronized
8x2 bi-directional MIMO environment for prototype testing in an
Advanced Projects lab. The next day you might need independent
2x2 MIMO test stands in separate labs. With the SR5500’s
“building block” architecture you can seamlessly move between
multiple simple test stands and the more concentrated capability
of a complex integrated system. No matter what configuration you
deploy, you’ll have a single intuitive interface that easily makes
use of all the SR5500’s unique advanced features.
Whether you choose a fully modular solution or a pre-configured
static system solution, your turnkey SR5500 system will be up
and running and ready to go upon delivery.
Some engineers like to personally choose the RF “plumbing”
required for bi-directional testing. For those who do not, the
optional RF Interface integrates all the circulators and splitters
necessary for integrated bi-directional MIMO testing, and adds
precise “dial-in” attenuation on a per-path basis.

Spirent’s Channel emulation history
When a fader is used in an initial large-scale technology
deployment, “getting it wrong” can make or break a business. In
these cases the selection of a fading emulator includes research,
rigorous evaluation and head-to-head comparative evaluations.
Spirent fading emulators were chosen for the world’s most
important rollouts of new wireless technologies, including the
first commercial deployments of 1x CDMA, WCDMA, FOMA, HSPA,
WiMAX, and several revisions of EV-DO. They were also behind
the development of the first RX Diversity device, the first Smart
Antenna system, the first MIMO proof-of-concept system, and are
currently used in developing LTE base stations and devices.
Spirent actively participates in dozens of industryleading organizations; here are just a few.
Spirent’s leadership in channel modeling has led to many
industry firsts, including: the first emulator to integrate I/O power
meters for accuracy, the first integrated AWGN, the first modular
RF channel emulation system, the first dynamic correlation
modeling and much more.
When your business depends on the quality of information you
provide, remember that the SR5500 is always the first choice in
business-critical deployments.
