National Instruments PXIe-6594 PXI High-Speed Serial Instrument
The PXIe-6594 is a PXI High-Speed Serial Instrument from National Instruments with 8 Digital I/O Channels. This instrument is suitable for a broad range of applications where validation of serial protocols is required. The NI PXIe-6594 features an integrated FPGA for the implementation and processing of numerous intensive serial protocols. This Serial Instrument is designed to support maximum transfer rates up to 28 Gbps, and it has a powerful Xilinx Kintex Ultrascale+ FPGA. This instrument is designed for PXI Express and requires 1 PXIe slot, allowing it to be used in a variety of compatible PXI Express Chassis.
The NI PXIe-6594 comes equipped with a CLK OUT connector and a CLK IN connector. This High-Speed Serial Instrument allows the user to employ the full advantages of PXI triggering and clocking. Moreover, you can enjoy high-speed data transfer facilities as well as the ability to induce peer-to-peer streaming and streaming from and to disk. The NI PXIe-6594 is fully compatible with LabVIEW FPGA, which means that the integrated FPGA can be easily configured through software. In this way, the user can reconfigure the High-Speed Serial Instrument for different tasks at different times. The 8 transmit (Tx) and 8 receive (Rx) lines incorporated in this instrument also operate through the multi-gigabit FPGA transceivers. The NI PXIe-6594 is one of the most user friendly instruments available for testing serial devices through PXI systems, making it an excellent choice for applications including the simulation of a variety of modern high-speed serial interfaces.
The maximum power requirements of the PXIe-6594 differ depending on the voltage level. The instrument draws 3 A at +3.3 V, and 4 A at +12 V. The total maximum power of the device measures at 58 W.
Physically, this High-Speed Serial Instrument is intended for indoor use only and has an ambient operating temperature range of 0 °C to 55 °C. When not in use, the ambient temperature for storage conditions ranges from -40 °C to 71 °C. Without including the connectors, the dimensions of the device measure 0.8 in. × 5.1 in. × 8.5 in. (2.0 cm × 13.0 cm × 21.6 cm) and it weighs in at 18.3 oz (520 g ).
