Spirent Vertex®
Channel Emulator
The Vertex® channel emulator is an advanced platform that replicates
the comprehensive noise and spatial conditions of even the most complex
wireless channels. Its cutting edge capabilities enable users to emulate
a real-world RF environment in the lab, making it possible to isolate and
identify performance issues early in the development cycle.
Vertex is backed by a long history of channel emulation leadership and
industry-recognized expertise. Incorporating a modular RF front end with
a powerful signal processing core, the Vertex channel emulator achieves
an unprecedented level of scalability and flexibility, enabling it to eciently
address a broad range of applications from low channel density like SISO or
2x2 MIMO to high channel density required for 5G scenarios, such as MIMO
beamforming, MIMO OTA, carrier aggregation, and massive MIMO.
Easy to set up and operate, Vertex includes Spirent’s industry-recognized
user-friendly graphical user interface that allows measurements to be set up
and performed quickly and accurately.
The world’s most scalable
channel emulation platform,
Spirent’s Vertex channel
emulator is an advanced test
and measurement system that
accurately simulates the complex
eects of signal fading on
wireless transmissions.
The system enables the test and
evaluation of a broad range of
applications with a variety of
channel densities, from basic
applications like 2-channel SISO
to complex, high channel density
applications like MIMO OTA,
MIMO beamforming and carrier
aggregation needed for 5G test
scenarios.
The Vertex platform combines
modularity, scalability and
ease-of-use into a powerful
test and measurement solution
that addresses the needs of
a constantly evolving wireless
market.

Features & Benefits
Scalability
The Vertex Channel Emulator is scalable to a broad range of applications. The hardware is capable of supporting
as few as two bidirectional RF channels for basic RF testing, and up to as many as 32 unidirectional RF channels to
support high channel density such as MIMO OTA, all in one single, small form instrument.

Low Channel Density
Modularity
Separate RF modules are optimized for unidirectional or
bi-directional applications and support a variety of dierent
frequency bands. This allows the Vertex Channel Emulator to
be configured for specific test needs using minimal hardware.
Field-replaceable RF and DSP modules facilitate upgrades
and enhance serviceability.
High Channel Density in a Compact Space
The Vertex Channel Emulator system supports up to 36 RF
ports and 256 digital links in one 6U rack height. It enables
more ecient use of hardware for tests that require higher RF
channel counts.
Comprehensive Channel Modeling Support
The built-in Vertex propagation library oers a vast selection
of standard channel models, while making it easy to edit and
save changes to both the standard as well as user-defined
models. Classical and 2D/3D geometrical channel models are
supported and the independent channel modeling feature
allows one Vertex to support up to 16 nodes for mesh network
applications.
Ease of Use
Complicated test setups are made simpler with an easyto-use Graphical User Interface (GUI). Intuitively-designed
libraries of connection setups make it easy to navigate through
complicated configurations by presenting information in a
clear way. For debugging purposes, important Information is
displayed in real time, including power level tracking of each
RF port.
High Channel Density
Remote Programming Interface (RPI)
Remote programming is supported through TCP/IP with both
telnet or SSH protocol. The RPI commands provide seamless
backward compatibly to the Spirent VR5 HD channel emulator.
Live Streaming Dynamic Environment Emulation
(LSDEE)
Live Streaming Dynamic Environment Emulation is an
advanced feature addition to the Vertex Channel Emulator
RPI. It provides a very high-speed control mechanism for an
extensive set of emulation parameters.
Unlike traditional DEE, which allows a user to create
predefined scenarios for modifying channel parameters
during a test run, there is no requirement to predefine or
pre-compile channel emulation states or inter-state durations.
LSDEE reduces processing time and monitors device behavior
to make real-time scenario adjustments. This is extremely
beneficial for high-speed scenarios where manual intervention
can interfere with time-sensitive environmental changes. The
same set of emulation parameters can be supported as with
traditional DEE.
