Analog Arts laptop powered USB SF series are affordable alternatives to the table top sized instruments at a fraction of the cost. The loop stability in a power supply design has always been a major concern for engineers. Having enough phase margins at specified gains guarantees this stability. A frequency response analyzer, FRA, can be used to analyze and verify the design at various stages of research and development. Nevertheless, its price could be a prohibitive factor in some situation. Furthermore, the power supply inherent switching noise distorts the frequency measurements. For this exact reason, Analog Arts has developed SF series family of product, affordable FRAs with an unprecedented level of performance. What makes the product line unique is the use of a self-adjusting narrowband filter to eliminate the noise from the signal. The technique provides measurements with better than .02 dB gain and .01 degree phase accuracy from 1 mHz to 150 MHz. In this family, SF880 offers a dynamic range of 100 dB from 1Hz to 10 MHz and SF900, for frequencies between 1 mHz to 1 KHz, delivers better than 110 dB noise free performance.
