National Instruments had released the new NI PXIe-5646R vector signal transceiver with 200 MHz of RF bandwidth designed 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. Powered by LabVIEW system design software, 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 ideally suited for the latest design and test techniques such as digital predistortion and envelope tracking.
