Description
The National Instruments PCIe-7852 is a multifunction reconfigurable I/O device, identified by part number 781103-01, and falls under the category of PC-based R Series. This device integrates seamlessly with R Series through a bus interface, showcasing its versatility in software interfacing.
One of the core features of the PCIe-7852 is its FPGA Logic, which is designed to provide timing, activating, processing, and custom I/O measurements. This capability allows for a high degree of flexibility and customization in handling various I/O operations. However, it’s important to note that the device does not retain VI (Virtual Instrumentation) after power-off. This means that the VI must be reloaded upon each power cycle, which could impact setup time in certain applications.
To mitigate this, the PCIe-7852 offers VI Load Options from onboard Flash memory or over the bus interface. The advantage of using Flash Memory is significant, as it allows the VI to start immediately after power-up, reducing downtime and increasing efficiency in operations that require frequent power cycling.
Moreover, the PCIe-7852 is equipped with various embedded I/O resources, including A/D converters (ADCs), D/A converters (DACs), and digital I/O lines. These embedded resources provide a comprehensive solution for a wide range of data acquisition and control applications, making the PCIe-7852 a versatile and powerful tool in any engineer’s toolkit.
