Overview – RF Synthesized Signal Generator
This RF synthesized signal generator covers a wide range of frequencies from 250kHz to 4GHz, which includes all of the commonly used RF bands. It is used for scientific research, production and RF testing as it has an extremely high frequency resolution, power accuracy and excellent spectral purity. Step sweep and list sweep provide flexible digital sweep functions which easily achieves control over output frequency and power. On UHF receivers, it can measure selectivity, sensitivity, inter-nodulation distortion, AM rejection, AGC response, audio hum, noise and distortion and STAND ratio.
