The Keysight M5302A is a single-slot PXIe digital I/O module engineered for high-speed data acquisition and real-time signal control in modular test systems. It provides 28 bidirectional LVDS channels operating at up to 1.2 Gbps, 8 bidirectional trigger channels for synchronization, and 4 general-purpose I/O lines. Built on a Xilinx Kintex UltraScale+ FPGA with 8 GB DDR4 memory, the module supports custom logic development via an optional FPGA sandbox area and enables protocol emulation such as Camera Link. The module connects via PXIe x8 Gen 3 peripheral interface and delivers trigger outputs of 0–3.3 V into high impedance loads or halved voltage into 50 Ω termination. LVDS channels drive 100 Ω differential loads and toggle at rates up to 1000 MHz. Full driver support spans IVI.NET, IVI-C, IVI-COM, and Python; PathWave Test Sync Executive enables multi-mode synchronization with real-time execution determinism across systems.
