before. The software also features
task-based instructions that simplify
complex system optimization and
measurements, and allow engineers
to more confidently validate their 5G
designs.
“R&D engineers at major wireless
infrastructure and device vendors are
designingandevaluating5Gcandidate
technologies using a complex range
of different tools,” said Mark Pierpont,
vice president of Keysight’s Internet
Infrastructure Solutions Group. “Our
new Signal Optimizer software solves
this problem by bringing together 5G
measurement science and flexible
wideband system calibrations in a
single software solution. The result
is a powerful 5G-focused solution
for accelerating deployment of the
fifth generation of mobile wireless
services.”
Keysight’s
Signal
Optimizer
software can generate and analyze
a host of 5G candidate technologies,
such as FBMC and F-OFDM.
Enhanced LTE for 5G is also being
developed along with new multiple
access on existing LTE signals.
Future additions are simply licensed
and added to the Signal Optimizer
software on an as needed basis.
NI Introduces Second-
Generation Vector Signal
Transceiver to Help Solve the
Most Demanding RF Design
and Test Applications
NI (Nasdaq: NATI), the provider of
platform-based systems that enable
engineers and scientists to solve
the world’s greatest engineering
challenges, today announced a
second-generation vector signal
transceiver (VST).The NI PXIe-5840
module is the world’s first 1 GHz
bandwidth VST and is designed
to solve the most challenging RF
design and test applications.
“NI redefined instrumentation in2012
by introducing the industry’s first
VST with an FPGA programmable
by LabVIEW to accelerate the pace
of design and lower the cost of
test,” said Olga Yashkova, program
manager for communications test
and measurement practice at Frost
& Sullivan.
The NI PXIe-5840 combines a 6.5
GHz RF vector signal generator, 6.5
GHz vector signal analyzer, high-
performance user-programmable
FPGA and high-speed serial and
parallel digital interfaces into a
single 2-slot PXI Express module.
With 1 GHz of bandwidth, the latest
VST is ideally suited for a wide
range of applications including
802.11ac/ax device testing, mobile/
Internet of Things device testing, 5G
design and testing, RFIC testing,
radar prototyping and more.
Product Features:
1 GHz of instantaneous bandwidth
for advanced digital pre-distortion
(DPD) test and wideband signals
such as radar, LTE-Advanced Pro
and 5G
Measurement
accuracy
that
enables systems based on the
second-generation VST to measure
802.11ac Error Vector Magnitude
(EVM) performance of -50 dB
Measurement speeds up to
10X
faster
than
traditional
instrumentation using FPGA-based
measurement acceleration and
highly optimized measurement
software
Small size and tight synchronization
allowing for up to 8×8 multiple input,
multiple output (MIMO) configuration
in a single 18-slot chassis
User-programmable FPGA that
engineers can easily design with
LabVIEW
The VST is a vital part of the
NI platform and ecosystem
that engineers can use to build
smarter test systems. These test
systems benefit from more than
600 PXI products ranging from
DC to mmWave. They feature
high-throughput data movement
using PCI Express Gen 3 bus
interfaces and sub-nanosecond
synchronization with integrated
timing and triggering. Users can
take advantage of the productivity
of the LabVIEW and NI TestStand
software environments, along with a
vibrant ecosystem of partners, add-
on IP and applications engineers,
to help dramatically lower the cost
of test, reduce time to market and
future-proof testers for tomorrow’s
challenging requirements.
