Vector signal generators (VSGs), analyzers (VSAs), and transceivers (VSTs) evaluate electrical signal characteristics across the frequency and time domain, measuring parameters like amplitude, phase, bandwidth, and modulation quality. They help engineers analyze complex waveforms in wireless communication system design, RFIC characterization, radar test, spectrum monitoring, and signals intelligence.
NI signal analyzers support baseband, RF, and mmWave frequency ranges so that you can choose the right option for your application. You can also choose options that include both baseband and higher frequency capabilities.
An NI Partner is a business entity independent from NI and has no agency or joint-venture relationship and does not form part of any business associations with NI.
With options that offer up to 4 GHz instantaneous bandwidth in a single acquisition, NI spectrum and signal analyzers are ideally suited for carrier aggregation, digital predistortion, and radar testing or for testing wireless standards, such as LTE-A Pro, and digital predistortion and radar pulse measurements.
NI PXI Vector Signal Transceivers can perform both spectrum analysis and RF signal generation in the same instrument. These options provide a compact solution for complex vector analysis and generation applications.
The PXI Vector Signal Analyzer (VSA) performs spectrum measurements, demodulation, and signal analysis—and can measure the magnitude and phase of an input signal at a certain frequency within a specified bandwidth.
The PXI Vector Signal Transceiver (VST) combines an RF and baseband vector signal analyzer and generator with a user-programmable FPGA and high-speed serial and parallel digital interfaces for real-time signal processing and control from baseband to mmWave.
The NI PXI Vector Signal Analyzer (VSA) is programmed using the NI-RFSA device driver. NI-RFSA includes APIs for LabVIEW or other text-based programming languages. NI-RFSA includes a soft front panel that you can use for quick measurements and debugging, or you can perform similar tasks using NI InstrumentStudio™ software. NI RFmx offers a variety of wireless test panels, specific to different types of measurements, in the InstrumentStudio environment. You can also choose to customize the onboard FPGA on the VSA using NI LabVIEW and the NI LabVIEW FPGA Module.
The NI PXI Vector Signal Transceiver offers similar software options. You can program the input channels of the device using NI-RFSA, and the output channels using NI-RFSG. You can also choose to use LabVIEW FPGA, InstrumentStudio, or NI RFmx.
A vector signal analyzer (VSA) measures and analyzes complex RF signals, focusing on modulation and spectrum characteristics. A vector signal transceiver (VST) combines a VSA with a vector signal generator, enabling both signal analysis and generation for design, test, and validation.
When choosing a vector signal transceiver, engineers should look for key features like wide frequency range to cover current and future standards, high bandwidth for complex signals, and excellent dynamic range for accurate measurements. Integration of fast signal generation and analysis, low latency for real-time testing, and flexible software support are also important for adapting to evolving technologies.
When selecting a vector signal analyzer, consider frequency range to match your application, bandwidth for capturing wide signals, and dynamic range for measurement accuracy. Look for advanced modulation analysis, fast processing, and versatile software to support evolving wireless and RF standards.
NI spectrum and signal analyzers offer speed, accuracy, and flexibility. They combine high-performance hardware with powerful software tools like LabVIEW for custom automation, RFmx for advanced modulation analysis, and NI TestStand for streamlined test management. This integration enables real-time analysis, wide frequency coverage, and scalable bandwidth, delivering faster testing, easier automation, and adaptability for future RF and wireless standards.
