The National Instruments PCI-5640R (Part number: 779460-01) is a robust Software-Defined Radio IF Transceiver designed for a variety of applications, including research, education, and communications. This device features two synchronized input channels and two synchronized output channels, each equipped with a 14-bit Analog-to-Digital Converter (ADC) and capable of real-time bandwidth up to 20 MHz. With a maximum sample rate of 100 million samples per second (MS/s) and a frequency range extending from 250 kHz to FM, the PCI-5640R delivers exceptional performance in processing signals.

As a PCI bus board, the PCI-5640R integrates seamlessly into desktop PC systems, providing users the flexibility to utilize either the onboard FPGA or host-based processing capabilities for efficient signal routing. The device is configured with two intermediate frequency (IF) inputs for receiving and two outputs for transmitting, supported by integrated up-converters and down-converters that facilitate baseband processing and offload computational demands. Programming and configuration of the device can be efficiently managed using the NI LabVIEW software along with the NI-5640R instrument driver.

Weighing 9.2 ounces with dimensions of 35.5 x 2.0 x 11.3 cm, the PCI-5640R operates with a power dissipation range of 20 to 25.5 Watts. Please note that while the PCI-5640R has been marked as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves.
