 Keysight Open RAN Studio – Solution Overview
Designed for LTE and 5G O-RAN Radio Unit (O-RU) testing, Keysight Open RAN Studio provides powerful,
yet easy to use, capabilities to:

• Build O-RAN compliant CUS-plane test vectors.

• Emulate an O-RAN Distributed Unit (O-DU) – to generate the test vectors against a
Device Under Test (DUT).
• Capture and accurately timestamp the DUT’s responses.
• Perform measurements needed to validate if the O-RU meets standard compliant
operation and radio performance.

Open RAN Studio includes powerful O-RAN focused tools to construct, play, capture, and measure
O-RAN traffic over 10 Gbps / 25 Gbps (fronthaul) Ethernet interfaces. Out of the box integration with
Keysight’s industry leading PathWave Signal Studio and 89600 VSA software enables sophisticated 5G
signal creation and easy capture, extraction, and export of IQ vectors – for advanced modulation analysis
of received RF / mmWave signals and radio performance. Additionally, when combined with Keysight
spectrum analyzers and signal sources, the integrated Open RAN Studio solution delivers the most
comprehensive cross domain, multi-channel RF / mmWave and O-RAN protocol measurements available
in the industry, for both FR1 and FR2 radios, downlink (DL) and uplink (UL) paths.

Keysight Open RAN Studio – Solution Components
Figure 1 (page 3) illustrates a simplified architecture for the Open RAN Studio suite
of integrated tools and optional elements, which include:

1. Signal Studio Pro for 5G NR creates 3GPP compliant 5G NR

waveforms for emulation through Open RAN Studio to an
O-RU / DUT and subsequent transmission to a downstream signal
analyzer, DUT, or compliant UE.
2. Open RAN Studio integrates five powerful O-RAN development
tools to construct, play, capture, measure, and extract IQ vectors
for split option 7.2x O-RAN traffic over a 10 or 25 Gbps fronthaul
Interface.
a. Open RAN Studio Builder helps you easily construct diverse
O-RAN test vectors. The PCAPNG formatted output file includes
the complete Ethernet / VLAN / eCPRI / O-RAN stack.
b. Open RAN Studio Player is a hardware-based exerciser that
emulates a DU and generates test vectors to an O-RU / DUT
through the O-RAN interface – honoring O-RAN CUS-plane
timing windows.
c. Open RAN Studio Capture is a hardware-based analyzer that
captures the bidirectional Tx and Rx information flows between
the DU and O-RU over the O-RAN interface.
d. Open RAN Studio Explorer decodes and visualizes the O-RAN
protocol information and enables measurement in both protocol
and RF / mmWave domains.
e. Open RAN Studio IQ Extractor is an optional application that
reconstructs a time domain IQ file from an O-RAN trace capture
for further modulation measurements with 89600 VSA software.
3. 89600 VSA for 5G NR may optionally receive captured IQ vectors
from Open RAN Studio IQ Extractor to perform 5G NR modulation
and radio performance measurements.

Keysight technologies is a founding member and active contributor

for O-RAN Alliance Work Group 4:

WG4 Open Fronthaul Interfaces – The objective of this work group is to deliver
truly open fronthaul interfaces, in which multi-vendor DU-RRU interoperability can
be realized. WG4 specifies an open front-haul interface (NGFI-I) between a DU
and RRU, based on C-RAN and xRAN’s work (IEEE 1914, eCPRI, CPRI).

Signal Studio Pro for 5G NR 2020, ORAN (N7631ORNC)

Keysight Signal Studio Pro for 5G NR software is a flexible signal creation tool that helps significantly
reduce the time spent on signal simulation. Quickly and easily generate 5G NR signals for component,
transmitter and receiver test. Its user-friendly interface lets you configure signal parameters, calculate the
resulting waveforms, and download .SCP files – for generation with Open RAN Studio Builder or for
analysis using Keysight 89600 Vector Signal Analysis software.

N7631C PathWave Signal Studio Pro for 5G NR enables you to generate various 5G NR signals
necessary to characterize the power and modulation performance of your components and transmitters.
Easily manipulate a variety of signal parameters to simplify signal creation.

Open RAN Studio Builder for O-RAN
Keysight Open RAN Studio Builder lets you quickly, easily, and reliably generate O-RAN test vectors
compliant with the ORAN-WG4.CUS.0-v02.00 specification. The generated test vectors represent Ethernet
based O-RAN messages from a distributed unit to the device being tested – the O-RU (Radio Unit).

Open RAN Studio Builder is integrated with PathWave Signal Studio Pro for 5G NR (N7631ORNC) to
create 3GPP NR standard-compliant signals and construct the corresponding Ethernet based O-RAN
protocol test vectors, including complete and consistent C-plane and U-plane messages, ready for playout.

Key Features:
• Fully automated generation of Ethernet based
O-RAN CU-plane messages with eCPRI
transport encapsulation types.
(ORAN-WG4.CUS.0-v02.00 Section 3.1, 3.2, 3.4)
• Predefined 3GPP test Patterns.
• Downlink stimulus test generation (CU-plane).
• Uplink stimulus test generation (C-plane).
• Multi-carrier support (up to 16 carriers).
• Generates a PCAP Next Generation based
stimulus file for use with Open RAN Studio
Player or Explorer. Figure 3: Open RAN Studio Builder C-Plane Setup

Downlink test vectors include both O-RAN C-plane and U-plane messages. C-plane messages are
constructed to fully represent the allocations defined in the 5G NR signal definition, and the U-plane
messages include frequency domain IQ for each resource block.

Uplink test vectors include only C-plane messages, as U-plane messages will be generated by the DUT.
To ensure consistency, the C-plane messages match with the uplink test signal generated by Keysight
signal sources.

Open RAN Studio Player for O-RAN
The Open RAN Studio Player software and integrated hardware appliance will playback Open RAN Studio
Builder generated stimulus files to an O-RU Radio Unit over an Ethernet based O-RAN interface. The
Open RAN Studio Player emulates and is seen by the DUT (O-RU) as an Open RAN DU. The Keysight
Open RAN Studio Player application is provided for use on a third-party 1RU Server Appliance (BittWare
TeraBox 1000S Server) running the Windows 10® Operating System and equipped with a specific FPGA
Interface Module loaded with the Keysight Open RAN Player FPGA build (BittWare XUP-P3R).

Key Features:
• Play Stimulus file once or repetitively.
• Real-time frame numbering.
• Real-time CRC Calculation.
• Dynamic Frame Numbering during playout.
• Reconfigurable DUT Destination MAC
Address.
• 10 Gbps to 25 Gbps Ethernet interface.
• SFP or QSFP support (quad QSFP cage).
• 3 GByte stimulus memory depth.

Figure 4: Open RAN Studio Player Interface Monitor

To ensure compliant frame synchronization, the Open RAN Studio Player can also act as a PTP master
and ensure that O-RAN messages are played honoring specified timestamps – enabling positive and
negative testing of required timing windows.

Open RAN Studio Capture for O-RAN
The Open RAN Studio Capture appliance is integrated within the Open RAN Studio Player hardware
appliance. It captures both Tx and Rx information flows between the DUT and DU – acting as an
embedded protocol analyzer by passively extracting the information flows traveling over the Ethernet
based O-RAN interface. Open RAN Studio Capture is transparent to the network and sees the O-RAN
flows as an Open RAN DU would. Captured flows are stored in a circular capture buffer and can be save
off as PCAP Next Generation compliant files for analysis in Open RAN Explorer or Wireshark.

Key Features:
• Start/stop Capture.
• Continuous capture mode until full
(last N frames).
• Full duplex capture capability.
o Stimulus transmitted on the downlink
o Uplink traffic from O-RU
• Configurable capture depth in # frames.
• Save captures in PCAPNG file format.

Open RAN Studio Explorer for O-RAN
Radio Units combine O-RAN protocol operation with RF transmit and receive performance, creating new
test challenges. Analysis and validation of O-RU performance requires cross-domain measurements in
both RF and Protocol domains.

With the optional Open RAN Studio IQ extractor, Open RAN Studio Explorer helps you visualize and fully
decode the captured trace and enables IQ centric extraction, which enables RF centric measurements
and vector analysis using Keysight 89600 Vector Signal Analyzer (VSA).

Key Features:
• Tx, Rx Bidirectional display.
• Accurate timestamped traces.
• U-plane and C-plane message summary.
• Full Stack Decoding.
• O-RAN Multiple Abstraction level.

PathWave 89600 VSA for 5G NR modulation analysis (89601BHNC)
The Keysight 89600 VSA software’s option 89601BHNC provides comprehensive analysis capabilities in
the frequency, time, and modulation domains for signals based on both 3GPP’s 5G NR specification
(www.3gpp.org) and Verizon’s 5G open trial specification (http://5gtf.org).

The software provides frequency-, time-, and modulation-domain analysis results in a single
