This unit
The Keysight U4301A is a modular PCIe protocol analyzer blade designed for high-speed capture and analysis of PCI Express traffic. It integrates into AXIe chassis systems and delivers packet-level decoding, transactional insights, and performance metrics across PCIe Gen 1, 2, and 3 links. The module supports lane widths from x1 to x16 and combines hardware probing with advanced analysis software to isolate protocol issues, training failures, and throughput bottlenecks in PCIe-based systems.
Technical Specifications
- Protocol Support: PCIe Generation 1, 2, and 3
- Lane Speeds: 2.5 GT/s (Gen 1), 5.0 GT/s (Gen 2), 8.0 GT/s (Gen 3)
- Lane Widths: x1, x2, x4, x8, and x16 configurations
- Capture Buffer: 4 GB per module (up to 8 GB for x16 links in specific configurations)
- Probing Technology: Equalization Snoop Probe (ESP) for high-speed accuracy
- Probe Options: Mid-bus probes, solid slot interposer probes (U4321A), flying lead solder-down probes (U4324A)
Key Features
- Transactional Decoding: NVMe and PCIe transactional analysis with directional and queue-based flow organization
- Performance Analysis: Real data throughput calculations and response-time measurements
- LTSSM Overview: Link Training & Status State Machine visibility for physical layer diagnostics and training sequence troubleshooting
- Lane View: Per-lane packet display with highlight capability
- Packet Viewer: Flexible color coding by packet type or direction; navigation viewer for rapid message access
- State-Based Triggering: Four-state sequence triggering with error detection on illegal sync characters, loss of framing, and illegal blocks
- Trigger I/O: External synchronization with complementary test instruments
Compatibility & Integration The U4301A installs as a modular blade in AXIe chassis systems, including the Keysight M9502A (2-slot) and M9505A (5-slot) platforms. Optional compatibility with Agilent AMP chassis is available. The flexible architecture supports configuration scaling for smaller test deployments.
Agilent / Keysight U4301A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight U4301A. Calibration covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight U4301A faults: power supply failure (cRIO-9073/9074), C-series slot connector wear, PXI chassis fan failure, GPIB interface failure on VXI controllers, BIOS/EEPROM corruption. NI CompactRIO most common faults are power supply failure on older cRIO-9073/9074 chassis and C-series module slot connector wear from repeated hot-swap cycles. PXI chassis fan failure is the most common wear item — chassis fans are field-replaceable. VXI embedded controllers most commonly develop EEPROM corruption and GPIB interface failure.
