### Technical Specifications

**Core Functionality:**
* **Over-the-Air Monitoring:** Real-time visibility into protocol and physical layer interactions in wireless transmissions.
* **Jitter and Signal Integrity Analysis:** While not explicitly detailed as a primary function in the provided search results, the “Agilent/Keysight SJ001A is a Jitter Test System” in the prompt suggests this capability. However, the detailed specifications found focus on wireless analysis.
* **Data Capture and Analysis:** Captures, stores, decodes, and analyzes all layers of wireless traffic.
* **Troubleshooting:** Essential for troubleshooting wireless network performance problems, including 5G, 4G, WiFi, and O-RAN networks. Isolates problem areas by triggering on lower- and upper-layer events, errors, messages, and message content.

**Wireless Technology Support:**
* **5G NR:** Supports 5G NR through 3GPP Release 18.
* **LTE:** Supports LTE and LTE-IoT.
* **Wi-Fi:** Supports Wi-Fi 7, Wi-Fi 8 (IEEE 802.11bn).
* **Other:** Supports NTN (Non-Terrestrial Networks), RedCap, NB-IoT, eMTC, C-V2X, and NR V2X. Also supports O-RAN and 3GPP standards.

**Performance and Capabilities:**
* **Multiple Ports for MIMO:** Supports up to 32 truly synchronized ports per coherent set, enabling testing of high-order MIMO configurations like 8×4, 8×2, or 4×4. For large-scale testing, up to 64 chassis (up to 256 modules) can be daisy-chained. Earlier documentation mentions support for up to 16 synchronized ports and 8×8 MIMO configurations.
* **Carrier Aggregation (CA) Bandwidth:** Supports up to eight Component Carriers of CA with up to 800 MHz channels.
* **Frequency Range:** Programmable frequency from 380 MHz to 11.4 GHz. The RXJudge2 Digital IF module provides connectivity for 2-11.4 GHz RF/IF testing.
* **Memory for Data Capture:** High memory capacity (RAM and SSD) allows for storing hours of IQ data, enabling tracking of long-term trends or isolation of intermittent anomalies. Flexible configuration options available.
* **Real-time Analysis:** Enables real-time triggering on lower- and upper-layer events, errors, messages, and message content for fast anomaly detection.
* **Synchronization:** Truly synchronized ports avoid time-consuming troubleshooting of alignment issues between devices. An internal system-wide master clock ensures proper sample count and timestamp alignment regardless of module or chassis density.
* **DSP and FPGA:** Utilizes the latest DSP cores, FPGA density, and technology-specific accelerators for real-time testing.

**Interfaces and Connectivity:**
* **Modular Chassis:** Features a modular chassis that can be customized and expanded.
* **PC Control:** Controlled by a laptop or desktop PC running SJ001A WaveJudge Wireless Analyzer Toolset software, connected via an Ethernet port.
* **Integration:** Integrates with other Keysight solutions (e.g., network, channel emulation, O-RAN test solutions) by importing and decoding IQ captures. Can also process PCAP captured from O-RAN fronthaul eCPRI interface. Can be combined with PathWave software for field-to-lab simulations. Can be added to non-signaling hardware like the E6680E wireless test set.

### Physical Characteristics

* **Modularity:** The SJ001A WaveJudge Wireless Analyzer Toolset is a modular system.
* **Scalability:** Scalable architecture allows for customization and expansion. Up to 64 chassis (up to 256 modules) can be daisy-chained for large-scale testing.

### Compatibility

* **Hardware Platforms:** Supported hardware platforms include WJ5000A WaveJudge wireless analyzer, WJ5900A WaveJudge 5G real-time wireless analyzer, and E6680E wireless test set (non-signaling test platform).
