Description
The NI PXIe-4498 is a high-precision PXI Dynamic Signal Analyzer (DSA) that is designed to meet the needs of a wide range of high-speed data acquisition applications. This device comes with part numbers 780218-01 and 780218-02, indicating its availability in multiple configurations to suit various requirements.
As a member of the PXI DSA category, the PXIe-4498 stands out with its exceptional performance and flexibility. It features a 24-bit delta-sigma ADC (Analog to Digital Converter), allowing for highly accurate data conversion at resolutions suitable for the most demanding applications.
The device boasts a remarkable sampling rate of up to 204.8kS/s (kilosamples per second), making it capable of capturing high-speed signals with precision. This is complemented by its 16 analog inputs, which provide the versatility needed to handle multiple signal sources simultaneously.
Users can also benefit from the PXIe-4498’s 4 selectable gain settings, allowing for optimal signal conditioning based on the amplitude of the input signals. This feature, combined with its AC-Coupled input coupling, ensures that the device can accurately process a wide range of signal types without distortion or loss of fidelity.
Another significant advantage of this DSA is its support for Transducer Electronic Data Sheet (TEDS). This enables automatic identification and configuration of connected sensors, simplifying setup and reducing the potential for errors.
The device’s flexibility extends to its triggering capabilities, with support for multiple trigger sources including analog input channels, external digital trigger input, and the PXI trigger bus. Its start trigger mode allows for precise synchronization of data acquisition tasks, while the 5 V TTL/CMOS-compatible trigger voltage ensures compatibility with a wide range of external devices.
In summary, the NI PXIe-4498 is a highly capable and versatile DSA module that offers top-tier resolution, sampling rate, and input capabilities. Its support for TEDS, along with flexible gain settings and comprehensive triggering options, make it an ideal
