VXG Series Microwave Signal Generators

Discover VXG Signal Generation

Keysight’s VXG provides a dual-channel vector signal generator with up to 110 GHz frequency range and 2.5 GHz of modulation bandwidth per channel to enable your next breakthrough.

Do more with less

The scalable architecture of the VXG signal generator enables higher frequency coverage, wider bandwidths, and multichannel applications with ease and accuracy. It allows you to reduce test complexity and achieve faster, repeatable results.

• Cover frequency ranges from 9 kHz to 110 GHz

• Generate the most demanding signals with the extremely wide modulation bandwidth

• Enable multi-antenna test applications such as MIMO and beamforming with precise phase coherence and timing synchronization

Measure with confidence

Keysight's fully integrated, calibrated, and synchronized signal generation solution helps you minimize measurement uncertainty. You no longer need to worry about errors introduced by complex test setups that require countless connections across multiple instruments. 

• Overcome excessive path loss at higher frequencies without sacrificing performance

• Deliver the best RF performance for accurately characterizing your device

• Enable precise multi-channel and multi-instrument synchronization

Generate True Performance

To know your device’s behavior, you’ll take many paths. Keysight’s VXGs produce the signals you need—from simple to complex, from clean to dirty—to test your design within and beyond its limits.

Industry-leading phase noise with DDS

The VXGs adopt a modern direct digital synthesis (DDS) design. The DDS architecture provides substantial phase noise improvements at wide offsets with extremely fine frequency tuning resolution. The VXG supports up to four coherent channels in one instrument and a controllable phase relationship between the channels.

Best dynamic range with direct RF architecture

With an advanced high-speed digital-to-analog converter (DAC) and digital signal processor, M9484C VXG’s DDS can generate signals up to 8.5 GHz direct from the 14-bit DAC without images. The direct DDS architecture eliminates signal impairments caused by the analog I/Q modulator, such as gain imbalance, timing skew, quadrature skew, DC offset, and phase noise. This new solution delivers the best dynamic range, especially for wideband signal generation.
