The National Instruments NI-5781 is a Transceiver Adapter Module designed specifically for FlexRIO systems, offering a versatile solution for high-performance signal processing applications. This module features a bandwidth of 40 MHz and is equipped with two differential input and two output channels, allowing seamless interfacing with baseband to RF up-converters and down-converters. It supports a maximum analog input sampling rate and analog output update rate of 100 MS/s. When paired with a compatible PXI FPGA Module, the NI-5781 provides a reconfigurable I/O baseband system suitable for a range of applications, including custom RF modulation, RF demodulation, bit error rate testing, channel emulation, and spectral monitoring or jamming.

Designed for high throughput and low latency, the NI-5781 leverages FPGA-based processing capabilities, making it ideal for inline processing and high-speed control tasks. This module is compatible with Virtex-5 FPGAs and supports DC input coupling. Each of the two channels operates at a fixed 2 Vpk-pk input range in differential mode and 1 Vpk-pk input range in single-ended mode. The module includes MCX type analog input connectors, each capable of handling ±2 V absolute maximum input with a 50 Ω input impedance.

The NI-5781 employs a multistage, differential pipelined architecture with 14-bit resolution and dual ADCs that enhance performance. Additionally, it is equipped with elliptic filters and supports NI-RIO device drivers and LabVIEW software, with optional integration into the LabVIEW Real-Time Module. This product comes with a comprehensive user manual and a maintenance manual available for download. For pricing information, please contact a sales representative. The dimensions of the module are 5.1 x 0.8 x 4.7 inches, and it weighs 10 oz. The NI-5781 is backed by a 2-3 year warranty.
