The Keysight M3100A is a PXIe digitizer module delivering high-channel-density data acquisition for automated test systems. This 3U modular instrument captures signals simultaneously across 4 or 8 channels at 100 MSa/s with 14-bit resolution and 100 MHz front-end bandwidth, storing up to 2 GB of data on-board. The M3100A integrates a Xilinx Kintex-7 FPGA (325T or 410T) for real-time signal processing, user-defined logic, and hardware-accelerated decision-making via Hard Virtual Instrumentation (HVI) technology.
