The Keysight M9033A is a double-width, 3U PXIe system synchronization module that distributes precise timing and synchronization across multi-module and multi-chassis test systems. Built around a Xilinx Virtex UltraScale+ VU3P FPGA and high-quality OCXO reference clock, it enables deterministic data acquisition and signal processing in distributed instrument architectures while adhering to PXI Express System Timing (STM) specifications.
