The NI PCI-5124 is a high-speed, 12-bit digitizer/oscilloscope for precise signal acquisition in demanding test and measurement environments. It delivers two simultaneously sampled analog input channels with real-time sampling up to 200 MS/s, or up to 4.0 GS/s using random interleaved sampling (RIS). With 150 MHz bandwidth and software-selectable input impedance (50 Ω or 1 MΩ), the device accommodates a wide range of signal types across independently configurable input ranges from 200 mVpp to 20 Vpp. The PCI-5124 employs National Instruments’ Synchronization and Memory Core (SMC) technology to achieve sub-nanosecond synchronization and high-speed PCI data transfer.
