Highlights

The SJ001A WaveJudge Wireless Analyzer Toolset allows design and verification engineers to gain visibility into protocol and physical layer interaction in wireless transmissions.

Combining powerful over-the-air capture of IQ data with real-time protocol decoding and PHY analysis, the SJ001A is an essential tool for troubleshooting and optimizing wireless networks in the field and in the lab. The SJ001A analyzes all received IQ data no matter the source making it an unbiased solution for evaluation of messaging between devices and base stations in development and deployment.

Keysight's SJ001A WaveJudge Wireless Analyzer Toolset is useful in several configurations:

  • Standalone software solution to analyze imported IQ data
  • IQ data capture, storage, decoding, and analysis of all traffic when combined with a WaveJudge wireless analyzer hardware platform, either the WJ5000A or the WJ5900A
  • Direct IQ data capture and storage with decoding and RF analysis of PHY and MAC layers when combined with Keysight's E6680E Wireless Test Set hardware

Key Software Features:

  • Decodes and analysis for all major wireless technologies such as 5G NR through 3GPP Release 18, NTN, RedCap, LTE, Wi-Fi, NB-IoT, eMTC, C-V2X, and O-RAN
  • RF/PHY and upper layer messages with timing correlated to RF chart views for efficient troubleshooting
  • Automatic error detection helps to find and resolve issues
  • Comprehensive coverage of KPIs provides insights of device and network performance

Key Hardware Features:

  • Independent, unbiased judge between vendors; all traffic decoded and analyzed regardless of the source
  • Passive monitoring of communication between all entities such as gNB, eNB, O-RU, UE, and access points
  • Find the issue at the very same moment it occurs with real-time analysis
  • Catch hard-to-find and intermittent issues with long capture times
  • Fast anomaly detection with sophisticated triggers
  • Testing of 5G NR FR1 and FR2 with bandwidth up to 800 MHz

Troubleshoot Challenging NTN Issues

Non-Terrestrial Networks (NTN) bring challenges like path loss, propagation delay, and time drift, making troubleshooting issues on the network harder. Rapidly capture IQ from different stages of the NTN chain, and analyze all layers from PHY/RF to L1-L3 using Keysight WaveJudge Wireless Analyzers. This solution decodes LTE, 5G, and Wi-Fi signals, offering real-time visibility into protocol and physical layer interactions to root cause issues, troubleshoot faster, and boost network quality.

WaveJudge User Interface

The WaveJudge offers a powerful graphical user interface that simplifies the test setup and configuration.

Using the GUI, you can:

  • Identify and analyze complex antenna schemes including MIMO and beamforming
  • Compare expected vs. received frame structure and identify allocation issues
  • Synchronize and reference signal errors
  • Visually inspect scheduler performance
  • Capture the attach process beginning with UL power
  • Trace the bytes as they move through the MAC, RLC, and PDCP layers
  • Correlate the timing of RF/PHY and protocol events in message and RF chart views
  • Perform detailed, symbol-level analysis in the 2D power diagram

Hardware Platforms

Three hardware platforms provide just the right solution:

  • WJ5000A WaveJudge wireless analyzer supports real-time LTE, NB-IoT, and eMTC analysis
  • WJ5900A WaveJudge 5G real-time wireless analyzer
  • E6680E wireless test set (non-signaling test platform)

Keysight's WaveJudge hardware platforms use a proprietary, modular architecture optimizing test coverage to meet the available testing budget. Scalable and high-speed programmable hardware may be updated and expanded to add RF ports or memory as testing needs change over time.

Keysight's E6680E Wireless Test Set is a non-signaling test platform providing RF signal generation and analysis with multiple transceivers. When combined with the SJ001A WaveJudge wireless analyzer toolset software, capture, storage, and analysis of lower-layer messaging correlated in time with RF results provide detailed troubleshooting of issues beyond RF performance without the need for expensive signaling test equipment.

Integrate WaveJudge Software with Additional Keysight Solutions

Keysight's SJ001A WaveJudge Wireless Analyzer Toolset software can be integrated with other Keysight solutions such as network, channel emulation, and O-RAN test solutions by importing and decoding collected IQ captures for detailed troubleshooting and full-stack protocol analysis. WaveJudge also processes PCAP captured from the O-RAN fronthaul eCPRI interface enabling troubleshooting of interoperability issues between O-RAN vendors. With this advanced capability, you can analyze and pinpoint PHY and protocol issues without depending on vendor analysis logs. This is particularly useful when logs from multiple vendors conflict, causing undue delays and increasing engineering expenses.

WaveJudge Integration with other Keysight Solutions

Characterize 5G NR RedCap Devices

RedCap stands for Reduced Capability 5G NR devices. 3GPP approved this new device type in Release 17 to make it easier for 5G to be used with IoT devices. The reduced 5G NR capability allows for reduced cost during development and manufacturing. Typically, IoT uses low-cost devices in applications such as wearables, industrial sensors, smart homes and cities, and security and surveillance.
