TECHNICAL
OVERVIEW
S8705A RF/RRM DVT and Conformance Toolset
Features and Capabilities
Around the world, commercial development and deployment of 5G technology
is accelerating to address a wide range of compelling use cases for consumers
and industry verticals. Device manufacturers need early and continuous access to
the latest 3rd Generation Partnership Project (3GPP) radio frequency (RF), radio
resource management (RRM), and protocol conformance test specifications to
accelerate 5G New Radio (NR) device certification. Conformance tests validated
by certification bodies help ensure that commercial 5G devices comply with the
latest 3GPP-defined specifications and operate as expected on mobile networks.
Governments also require radio devices to comply with regulations via testing at
accredited labs before products become available in the market.
The Keysight S8705A RF/RRM DVT & Conformance Toolset is part of Keysight’s
Network Emulation Solutions (NES) portfolio. The portfolio addresses the entire
device RF development workflow — from initial design to acceptance.

RF/RRM DVT & Conformance Toolset Overview
The S8705A RF/RRM DVT & Conformance Toolset is an integrated solution that enables
RF performance testing of 5G devices against the 3GPP-defined conformance test
specifications across frequency range 1 (FR1, sub-6 GHz) and frequency range 2 (FR2,
millimeter wave, or mmWave). The solution also supports test cases for cellular vehicle-
to-everything (C-V2X) communication based on Long Term Evolution (LTE) and LTE
sidelink formats.
The solution offers two configurations to adapt to different needs:
• The Design Verification Test (DVT) configuration provides unvalidated test cases
based on the 3GPP test specifications. Their purpose is to allow the customization
of the baseline test methodologies and test limits from 3GPP to test the device
beyond industry requirements, explore its performance limits, and compare its
performance against competitive devices to enhance the end user experience.
• The Conformance configuration provides test cases validated at relevant industry
certification bodies, such as the Global Certification Forum (GCF) and the PCS Type
Certification Review Board (PTCRB). This configuration also supports test plans from
regulatory bodies that local authorities enforce before product deployment.
When testing 5G NR RF characteristics, the scope expands from in-band test cases
to out-of-band measurements such as spurious emissions and blocking. In-band test
cases focus on the radio’s performance as a transmitter and receiver. Out-of-band
measurements help determine how the device’s radio impacts other devices operating
in the same or adjacent bands. Out-of-band measurements also assess resistance to
interference from nearby radio devices.
The toolset also covers RRM and performance testing, which are essential for fully
characterizing the RF performance of devices. RRM helps confirm that the device
can keep a robust and reliable connection to the network in stationary and mobility
scenarios, with handovers between cells using the same or different radio access
technologies. Performance testing checks that the device can successfully demodulate
downlink signals under ideal or impaired radio conditions, with special tests defined for
channel state information (CSI) reporting.
To support 5G’s diverse set of test requirements, the RF/RRM DVT & Conformance
Toolset leverages the superior RF measurement and real-time processing capabilities of
Keysight’s E7515B UXM 5G wireless test platform. The platform also allows RF testing
in adjacent bands (that is, adjacent channel leakage ratio), generates interferers for
blocking test cases, including additive white Gaussian noise (AWGN), and provides
fading without the need for additional instruments in the test system. Find more details
