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.
