NI PXI-2557 is a high-performance data acquisition module produced by NI (National Instruments) company. The following are some of the main features and functions of this module:
High speed data acquisition: Supports a sampling rate of up to 500 MS/s, enabling fast data acquisition and high-frequency signal analysis.
Multi channel configuration: With 4 independent input channels, it can simultaneously collect multiple signal sources, achieving multi-channel data acquisition and synchronous measurement.
High resolution: Provides 16 or 14 bit ADC (analog-to-digital converter) resolution for accurate signal acquisition and measurement.
Large capacity storage: Built in large capacity sampling memory, which can be used to store a large amount of sampling data and support long-term data collection.
Flexible input range: Supports different input range configurations to meet the measurement needs of different signal strengths and levels.
Programmable gain: With programmable gain control function, signal amplification or attenuation can be carried out according to actual application needs.
PXI bus interface: Adopting a standard PXI bus interface, it seamlessly integrates with other PXI modules and devices, facilitating system expansion and interconnection.
Driver software support: The NI PXI-2557 data acquisition module is equipped with driver software suitable for various programming environments, such as LabVIEW and NI-DAQmx, making it convenient for users to quickly develop and integrate.
