Keysight / Agilent / HP N5315A-A16 Slot Interposer Probe

The Keysight N5315A-A16 is an analog repeating slot interposer probe that enables mid-bus signal access to PCIe interfaces in space-constrained environments. This probe connects directly to PCIe slots without signal distortion, allowing logic analyzers to capture and analyze live bus traffic during system operation. The design maintains electrical idle propagation integrity and supports all standard PCIe link widths - x1, x4, x8, and x16 - making it compatible across diverse PCIe endpoint configurations. The interposer incorporates dual mechanical stabilization features: one for the endpoint device and one for the backplane connection. These stabilizers ensure a firm, reliable fit within the PCIe slot, preventing signal reflections caused by loose contacts. The probe integrates directly with the Keysight N5306A PCIe Analyzer Module for protocol-level analysis and deep packet inspection.
