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 RF/PHY and Protocol events in message and chart views
- Perform detailed symbol level analysis in 2D power diagram
WaveJudge Hardware Platform
The SJ001A WaveJudge Wireless Analyzer Toolset uses a proprietary, modular architecture that is much more targeted and cost-effective than a one-size-fits-all standard platform, allowing to maximize the coverage according to testing budget. Scalable and high-speed programmable hardware to update and expand the solution in terms of ports or memory as needs change in terms of MIMO or carriers use cases. For large-scale testing up to 64 chassis can be daisy-chained to house up to 256 modules.
WaveJudge Integration with other Keysight Solutions
SJ001A WaveJudge Wireless Analyzer software can be integrated with other Keysight Solutions like Network, Channel Emulation and O-RAN Test Solutions by importing and decoding collected IQ captures for detailed troubleshooting and full stack protocol analysis. WaveJudge can also process PCAP captured from O-RAN Fronthaul eCPRI interface enabling troubleshoot for the interoperability issues between O-RAN vendors. With this advanced capability, you can analyze and pinpoint PHY and protocol layer issues without having to be dependent on vendor analysis logs. This is particularly useful when logs from multiple vendors conflict, causing undue delays and increasing engineering expenses.

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. Learn more about how our Wireless Network Emulation Solutions help to reduce cost while performing functional and RF tests on RedCap devices.
