NI brings baseband model of Vector Signal Transceiver

NI PXIe-5820 module
Test and measurement company NI today announced a baseband model of the Vector Signal Transceiver (VST).

The PXIe-5820 module, the industry’s first baseband VST with 1 GHz of complex I/Q bandwidth, is designed to address the challenging RF front-end module and transceiver test applications, such as envelope tracking, digital pre-distortion and 5G test.

In 2016, NI introduced the RF model of our second-generation VST with 1 GHz of instantaneous bandwidth.

“Engineers can take advantage of the software-designed architecture of NI’s VSTs to help accelerate the pace of design, reduce the cost of test and solve measurement problems previously unsolvable through traditional test approaches,” said Charles Schroeder, vice president of RF and wireless at NI.

The PXIe-5820 combines a wideband I/Q digitizer, wideband I/Q arbitrary waveform generator and high-performance user-programmable FPGA into a single 2-slot PXI Express module.
NI 5G testing solution
Earlier this week, NI announced 5G testing solution.

The baseband VST suits a wide range of applications including baseband I/Q testing of wireless and cellular chipsets as well as envelope tracking of digitally pre-distorted waveforms for power amplifier, and generation and analysis of new wireless standards such as 5G, 802.11ax and LTE-Advanced Pro.

“The baseband VST can be tightly synchronized with the PXIe-5840 RF VST to sub-nanosecond accuracy, to offer a complete solution for RF and baseband differential I/Q testing of wireless chipsets,” said Ruan Lourens, chief architect of R&D, RF at NI.
