MWC 2014: NI brings software-designed test to LTE-A mobile
National Instruments has introduced the next PXI Express-based instruments in its software designed RF transceiver range.
Demonstrated this week at Mobile World Congress 2014, the PXIe-5646R vector signal transceiver has 200MHz of RF bandwidth which will allow it to support the testing of wireless standards such as IEEE 802.11ac, 160 MHz WLAN and LTE Advanced.
Functions which can be software designed on the vector signal transceiver (VST) include radio channel emulation, radio prototyping and custom real-time signal processing for spectrum analysis.
The software-designed instrument, which is LabView RIO architecture, combines a vector signal generator and vector signal analyser with a user-programmable FPGA into a single PXI modular instrument.
As a result LabView is used to design system functions and test routines running on the FPGA-based hardware for specific mobile and other wireless applications.
The 5646R offers has a maximum sample rate of 250MS/s, which will easily meet the needs of the standard LTE radio frame and also test techniques such as digital predistortion and envelope tracking.
