概要（Overview）

Use the Doble M5400 Sweep Frequency Response Analyzer to detect mechanical failure or movement of windings due to short circuits, mechanical stresses or transportation. Sweep Frequency Response Analysis is a proven technique, pioneered by Doble, for making accurate and repeatable measurements. The sweep approach is the industry standard and the preferred method for making frequency domain measurements. Coupled with the ease of use and powerful features of SFRA Software v6, conducting SFRA testing and analysis of your apparatus has never been easier or more productive.
