      Information

      Overview Manuals Working principle Application & Integration

      Features:

      • High-resolution, 14-bit digital oscilloscope (digitizer)
      • Designed for PCI-based automated test and measurement systems
      • Used for tasks requiring precise time-domain and frequency-domain analysis
      This module features two synchronous sampling channels with 14-bit resolution and a maximum real-time sampling rate of 100 MS/s, making it ideal for high-precision, wide dynamic range, and high-frequency signal acquisition. This powerful module offers a wide input range of 200 mV to 20 V and abundant onboard memory options, enabling lossless acquisition of signals with long durations and complex waveforms.

      It is fully integrated with NI-SCOPE driver software, allowing seamless synchronization with other instruments via the PXI/PCI bus, and supports advanced trigger modes for precise signal isolation and analysis.

      The PCI-5122 NI NATIONAL INSTRUMENTS Digital Calibration Procedure may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      NI NATIONAL INSTRUMENTS PCI-5122 Digital Calibration Procedure manual(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
      In terms of operation, the PCI-5122 first scales and filters the input analog signal through a high-fidelity front-end circuit before sending it to a high-speed analog-to-digital converter (ADC). These ADCs sample the signal at fixed time intervals, converting instantaneous voltages into 14-bit digital data. The data is then transferred to the onboard memory via a high-speed controller that uses a reference clock to manage timing and synchronization, ensuring jitter-free data acquisition on both channels.
      1. Software Compatibility: Fully integrated with NI LabVIEW, LabWindows/CVI, and Measurement Studio. It uses the NI-SCOPE driver, which includes over 50 built-in measurement and analysis functions.
      2. Common Applications: Used for ultrasonic and radar signal processing, event detection, and high-channel-count simultaneous measurements when multiple modules are connected.
      3. Physical Configuration: Requires a standard PCI expansion slot. It features a BNC female connector for analog inputs and external triggering.
