National Instruments PXIe-5644R PXI Reconfigurable Vector Signal Transceiver

The PXIe-5644R (Part Number: 782376-01, 784757-01) is a Reconfigurable Vector Signal Transceiver from National Instruments. Also known as just PXIe-5644, this device integrates features of real-time signal processing and control into one convenient device. Equipped with 80 MHz of bandwidth, the NI PXIe-5644R offers high-speed processing and reliable signal fidelity. The two part numbers for the device differ in their relevancy. Part number 782376-01 is the standard version of the device, while part number 784757-01 describes the legacy variation.

The Xilinx Virtex-6 LX195T FPGA of the PXIe-5644R boasts 12,384 kbits of embedded block RAM, offering plenty of flexible space for system configuration. The transceiver includes a range of SMA female connectors designated for specific applications- including RF OUT, RF IN, REF OUT, REF IN, LO IN, LO OUT, CAL IN/CAL OUT, DIGITAL I/O, and PFI 0.

The power consumption of the NI PXIe-5644R vector signal transceiver is drawn from both power connectors on the PXIe backplane. While the typical power draw is 56 W, the typical and maximum current differ depending on the power rail that is used. For a voltage of 3.3 VDC, the PXIe-5644R has a typical current of 4.9 A and a maximum of 5.3 A. A voltage rail of 12 VDC, on the other hand, has a typical current draw of 3.3 A and a maximum of 4.2 A.

Built for indoor use only, the NI PXIe-5644R has a recommended operating temperature range of 0 °C to 55 °C with a noncondensing relative humidity range spanning from 10% to 90%. When not in use, the device can be safely stored in an even wider temperature range of -40 °C to 71 °C, within relative humidity ranging from 5% to 95% (also noncondensing).

The 3-slot PXIe-5644R measures dimensions of 6.1 cm × 12.9 cm × 21.1 cm (2.4 in × 5.6 in × 8.3 in), and it weighs an easily manageable 1,360 g (48.0 oz).
