NI PXIe-5646R

Built for RF Automated Test and Measurement 

The PXI Vector Signal Transceiver (VST) combines a vector signal analyzer and vector signal generator with a user-programmable FPGA and high-speed serial and parallel digital interfaces for real-time signal processing and control. With up to 1 GHz of instantaneous RF or complex I/Q bandwidth, the NI VST is ideally suited for a wide range of applications including RFIC validation and production testing, radar prototyping, and other RF wideband test scenarios.

The VST product line provides the high performance necessary to support lab design and validation applications and incorporates the fast measurement speed and small form factor required to scale to production test applications. You can use VST instruments throughout the design cycle from design, to validation, to production test – minimizing measurement correlation errors and improving efficiency with test software reuse. The VST can be used to test a variety of cellular and wireless standards including 5G NR, Wi-Fi 6, and Bluetooth. The modular PXI platform allows users to configure systems with multiple VSTs in order to support multiple input, multiple output (MIMO) applications, and simplifies synchronization between instruments thanks to shared timing and synchronization resources in the PXI chassis.

Key Features:

• Generate and acquire wide instantaneous bandwidth from baseband through RF in one instrument for test and measurement
• Ensure test coverage for new and legacy wireless standards, including 5G NR and all Wi-Fi bands
• Stream high-speed data to and from the instrument through front panel Digital I/O
• Achieve better than -50dB EVM performance for higher order modulation schemes, such as Wi-Fi 6
• Synchronize multiple VSTs with phase-coherent generation and acquisition for true MIMO applications.
• Utilize I/Q baseband signals for wideband testing and envelope tracking applications
• Get maximum test speed and customization with access to onboard FPGA
• Take advantage of easy to use software with soft front panels for interactive control and extensive measurement API for rapid test automation
