NI PCI-5124 high-speed digitizer

NI PCI-5124 high-speed digitizer

Performance parameters
Sampling rate: It features a real-time sampling rate of 200MS/s. Through random interleaved sampling technology, the effective sampling rate can be extended to 4.0GS/s, which can meet the requirements of high-speed signal acquisition.
Resolution: 12-bit resolution, which can precisely convert analog signals into digital signals, helping to accurately capture the details of the signals.
Number of channels: Dual synchronous sampling channels based on the PCI bus can synchronously collect two signals simultaneously, making it suitable for application scenarios that require simultaneous monitoring of multiple signals.
Bandwidth: Both input channels have a bandwidth of 150MHz, which can accurately collect high-frequency signals and ensure signal integrity.
Parasitic dynamic range: With a parasitic dynamic range of up to 75dBc (SFDR), it can effectively suppress stray components in the signal, enhancing the accuracy and reliability of the measurement.
On-board memory: The standard configuration is 8-256MB of large-capacity on-board memory, based on the NI Synchronization and Storage Core (SMC) architecture, with 512MB of on-board memory per channel. It can achieve fast data transfer and tight synchronization functions, and support long-term data acquisition and storage.

Functional characteristics
The input impedance is selectable: The 50Ω and 1MΩ input impedances selected by the software can adapt to different signal source impedances, facilitating connection with various devices.
Rich trigger modes: It includes multiple trigger methods such as edge, window, hysteresis, video and digital, with 5 trigger modes. Among them, the video trigger function can conveniently collect and analyze video signals, meeting the precise trigger requirements in different application scenarios.
Powerful synchronization function: Based on the SMC architecture, engineers can synchronize modular instruments based on SMC within tens of picoseconds (ps), which is suitable for high-channel and mixed-signal applications and facilitates the construction of complex multi-channel data acquisition systems.
