1. Processing Power: The PXI-8109 boasts a remarkable ability to process 129,000 1K Fast Fourier Transforms (FFTs) per second, making it approximately 20 percent faster than its predecessor, the NI PXI-8110 embedded controller.

2. Hardware Design: Equipped with state-of-the-art packaging, the PXI-8109 seamlessly integrates the Intel Core i7-620M processor and standard/extended PC I/O ports into a single unit. This one-piece controller design minimizes integration challenges and eliminates the need for complex cabling to daughterboards.

3. Peripheral I/O: Featuring high-performance peripheral I/O, the PXI-8109 includes two Gigabit Ethernet ports, four Hi-Speed USB ports, an IEEE 1284 ECP/EPP parallel port, RS232 port, and an integrated GPIB (IEEE 488) controller. This design ensures connectivity without sacrificing active slots in the chassis.

4. In-ROM Memory and Diagnostics: Enhancing serviceability, the PXI-8109 offers In-ROM diagnostics for quick access to hard drive and memory health. This feature allows for field replacement of critical components like the hard drive and memory without affecting the warranty, making service and maintenance more efficient.

5. ExpressCard Slot: The embedded controller features an ExpressCard/34 slot, utilizing PCI Express and Hi-Speed USB interfaces to provide up to 2.5 Gbit/s of bidirectional throughput. This slot offers flexibility for adding a third Gigabit Ethernet port or additional peripheral I/O options.

6. Video Capabilities: With an integrated ATI Radeon E2400 graphics processing unit, the PXI-8109 delivers realistic 3D graphics without the need for an additional video card. The controller supports dual monitors simultaneously, with a DVI-I video connector compatible with both digital (DVI) and analog (VGA) monitors.

7. Dual Monitor Support: The DVI-I video port supports simultaneous DVI and VGA output, allowing you to connect two analog monitors to your PXI system independently. This eliminates the need for a separate video module, providing a convenient dual-monitor setup.

8. Memory Configuration: Powered by dual-channel 1066 MHz DDR3 SDRAM, the PXI-8109 is ideal for data-intensive applications. Standard configuration includes 2 GB of RAM with options for upgrades up to 8 GB.
