TEST & MEASUREMENT HANDBOOK
Test instruments tackle 5G
Engineers responsible for designing and
manufacturing 5G chipsets, devices, and
systems have more than enough challenges.
From a technical standpoint, they must
deliver high bandwidth, low latency, and
other performance benchmarks. They also
must meet the corporate business case for
5G – cost and profitability. So they must
efficiently verify products according to the
3GPP Release 15 specifications to meet key
performance indicators (KPIs) in the most
timely and economical manner possible.
The high frequencies involved in 5G will force a re-think
of how to go about characterizing circuits and systems.

Signal analyzers such as the MS2850A
target applications in next-generation
broadband and multicarrier
communication systems found in 5G
mobile and broadcast satellites. Features
include built-in 5G measurement
software, 5G NR/V5G (sub-6 GHz/
mmWave) coverage, a wide dynamic
range to bring high EVM performance
(EVM: <1%), one-button dynamic-range
optimization at EVM measurements,
amplitude/phase/timing difference
measurements for each carrier, and a flat
amplitude and phase characteristic.
Test instruments will be important in
reaching these goals. Test solutions must
address the requirements of measuring
present-day 5G signals yet have the
flexibility to meet future versions of the
3GPP specifications as they continue to
advance.
DEVELOPING TEST PROCESSES
Compared to 4G LTE, 5G technology
brings greater capacity, lower latency,
and a more uniform user experience. No
universally approved 5G test standards
have been adopted -- test specifications
are evolving. But 5G testing parameters
