The National Instruments PCI-4452 (Part Number: 778317-01) is a sophisticated Dynamic Signal Acquisition Device designed for high-performance data acquisition applications. It features an integrated Measure function, which facilitates information acquisition and instrument control directly within Microsoft Excel. This function allows users to easily gather data from DAQ boards, GPIB instruments, and RS-232 devices using intuitive dialog boxes for configuration. Users can seamlessly input their data into Excel worksheet cells, leveraging the software's analytical capabilities for advanced data exploration and reporting.

The PCI-4452 supports four differential inputs that can be configured as referenced single-ended channels with the BNC-2140 DSA accessory. In differential mode, one line connects to the positive input, while another connects to the negative input of the same channel, enabling enhanced measurement quality by minimizing common-mode noise when interfaced with floating sources. The device is equipped with a programmable switch that determines whether a capacitor is included in the signal path. When configured for DC coupling, the capacitor is bypassed, allowing any DC offset present in the source signal to be transmitted directly to the analog-to-digital converter (ADC).

With a resolution of 16 bits and a versatile sample rate range of 5 kS/s to 204.8 kS/s, the PCI-4452 caters to diverse measurement needs. It features a 68-pin VHDCI female connector for analog I/O. Although the PCI-4452 has been designated as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves. The device comes with a warranty of 2-3 years, and users can access the user manual and maintenance documentation for further guidance. For pricing information, please contact a sales representative.
