Noise Figure Measurement

A stable frequency source is a common need for many electronic devices and most RF equipment. Phase noise can be used to characterize the short-term frequency stability of these frequency sources. Siglent’s SSA5000A Spectrum analyzers now provide a one-button phase noise measurement. The SSA5000A features lower Display Average Noise Level (DANL) and phase noise ensuring the accuracy of your tests. The smaller resolution bandwidth avoids measuring both carrier power and noise power together, and the measurement results are automatically calculated and graphed. The use of a logarithmic scale for the horizontal coordinate gives both a wider frequency range and finer resolution when close to the carrier – smaller offsets tend to reflect the quality of the signal better than phase noise at larger frequency offsets.

Accurate measurement of noise figure is crucial in product development and manufacturing. In the field of research and development, high test accuracy can ensure high repeatability between design simulation and real measurement and help to find the noise sources that are not considered in the simulation process. In the field of production and manufacturing, higher test accuracy means that the index margin can be set smaller when setting and verifying the technical index of the device. The higher the technical index of the final product, the more competitive it will be in the market. Quantifying those unknowns depends on flexible tools that provide accurate, reliable results. The noise figure measurement function of SIGLENT SSA5000A provides engineers with a simple tool, which can quickly and effectively measure the noise figure with high accuracy. Engineers can characterize noise figure and gain of connectorized devices and system blocks with graph, meter, and table layouts, and support the measurement of noise factor, Y-factor, effective temperature, and hot/cold power density.
