Scalable RF transceivers for high-performance, multiport testing
Keysight multiport RF vector transceivers are now offered in one capability class, the VT7-class, and include the E6400A Series and S9160A multiport RF vector transceivers. These transceivers deliver scalable, high-performance 5G testing with up to 64 phase and time-coherent RF transceivers, simplifying MIMO and beamforming validation. Supporting frequencies up to 7.25 GHz and 200 MHz of bandwidth per port, the platform supports a wide range of deployment scenarios without requiring hardware changes. High signal fidelity ensures accurate testing of complex modulation schemes, while the modular architecture makes it easy to upgrade as wireless standards evolve.

Frequently asked questions
A phase and time-coherent RF signal refers to multiple RF signals whose waveforms maintain consistent and stable phase relationships along with precisely synchronized timing.
Specifically, phase coherence ensures that the relative phase difference between individual signals remains constant, even as signals propagate or conditions vary, while time coherence guarantees that signals align accurately in terms of their timing and arrival at a receiver or target. This coherence is critical for advanced RF technologies such as massive MIMO and beamforming, where signals from multiple antennas must combine constructively to form precise signal beams, maximizing signal strength and enhancing communication range and quality.
It also plays a key role in radar systems, where accurate phase relationships are essential for target detection, imaging, and direction finding. Without consistent phase and timing coherence, systems can experience performance degradation, reduced accuracy, signal interference, and diminished reliability, particularly in high-frequency and high-bandwidth applications.
EVM in RF testing is a metric that quantifies the accuracy and integrity of digitally modulated RF signals by measuring how closely a transmitted or received signal matches its ideal reference signal. Specifically, EVM captures the difference between the ideal constellation points—the theoretical positions that digital signals should occupy—and the actual measured points, typically expressed as a percentage or in decibels (dB).
This measurement is crucial for assessing signal quality, verifying compliance with communication standards such as LTE, 5G, and Wi-Fi, and evaluating transmitter and receiver performance. Factors like phase noise, amplifier nonlinearities, interference, and calibration inaccuracies can degrade EVM performance. Lower EVM indicates a higher-quality signal, while higher EVM values suggest increased distortion, potential communication errors, and reduced overall system reliability.
RF conformance tests are standardized evaluations used to ensure that wireless devices comply with the specified performance and interoperability requirements defined by regulatory and industry standards, such as those set by 3GPP, IEEE, or FCC. These tests verify critical RF parameters, including transmit power, spectrum emissions, modulation accuracy (EVM), receiver sensitivity, adjacent channel leakage, blocking performance, and protocol compliance.
The primary purpose is to ensure reliable operation, interoperability with other devices and networks, and adherence to regulatory requirements, thereby reducing interference and maintaining consistent network quality. Devices undergoing RF conformance tests typically include smartphones, IoT equipment, network infrastructure, automotive communication modules, and other wireless systems. Passing these tests is essential for commercial deployment, regulatory approval, and certification, ensuring devices function properly within their intended environments.
