Vector signal transceiver takes on demanding RF design and test applications
Second-generation vector signal transceiver, PXIe-5840 module is claimed by National Instruments to be the first 1 GHz bandwidth VST and is designed to solve challenging RF design and test applications.
This transceiver combines a 6.5 GHz RF vector signal generator, 6.5 GHz vector signal analyser, high-performance user-programmable FPGA and high-speed serial and parallel digital interfaces into a single 2-slot PXI Express module. With 1 GHz of bandwidth, the latest VST is suited to a range of applications including 802.11ac/ax device testing, mobile/Internet of Things device testing, 5G design and testing, RFIC testing and radar prototyping.
The transceiver includes 1 GHz of instantaneous bandwidth for advanced digital pre-distortion (DPD) test and wideband signals such as radar, LTE-Advanced Pro and 5G. Its measurement accuracy enables the second-generation VST to measure 802.11ax error vector magnitude (EVM) performance of -50 dB.
It uses FPGA-based measurement acceleration and optimised measurement software and
small size and tight synchronisation allows for up to 8×8 multiple input, multiple output (MIMO) configuration in a single 18-slot chassis. User-programmable FPGA means that engineers can easily design with LabVIEW.
The VST is a vital part of the NI platform and ecosystem that engineers can use to build smarter test systems. These test systems benefit from more than 600 PXI products ranging from DC to mmWave. They feature high-throughput data movement using PCI Express Gen 3 bus interfaces and sub-nanosecond synchronisation with integrated timing and triggering.
Users can take advantage of the productivity of the LabVIEW and NI TestStand software environments, along with a vibrant ecosystem of partners, add-on IP and applications engineers, to help lower the cost of test and reduce time to market.
