March 3, 2014. National Instruments has announced the NI PXIe-5646R vector signal transceiver with 200-MHz of RF bandwidth, making it suitable for testing the latest wireless standards such as IEEE 802.11ac, 160-MHz WLAN, and LTE Advanced. Engineers can use the open software design of the vector signal transceiver to develop channel emulation systems, radio prototyping, custom real-time signal processing for spectrum analysis and many other applications.
NI vector signal transceivers combine a vector signal analyzer with a vector signal generator and a user-programmable FPGA for real-time signal processing and control. Customers have seen 10X to 100X improvements in test time in applications such as power-servoing in power-amplifier test by taking advantage of the speed, deterministic processing, and inherent parallel architecture of the FPGA. Built on the NI LabVIEW RIO architecture, the vector signal transceiver combines programming flexibility and the latest RF hardware to revolutionize mobile technologies test. The NI PXIe-5646R offers 200 MHz of complex bandwidth via a sample rate of 250 MS/s, which is greater than eight times the data rate for the standard LTE radio frame. This makes the vector signal transceiver suited for the latest design and test techniques such as digital predistortion and envelope tracking.
The NI PXIe-5646R is powered by LabVIEW system design software and provides the ideal platform to simplify modern design and test challenges.
