File name 5992-0198EN Measuring High Impedance Sources Using the U8903B Audio Analyzer - Application Note c201

Keysight Measuring High Impedance Sources Using the U8903B Audio Analyzer Application Note Introduction This note details the input impedance of the U8903B Audio Analyzer, and shows that this needs to be understood and carefully considered when measuring high impedance sources. A method of using an impedance matching attenuator to overcome high impedance measurement problems is described and a simple accessory is demonstrated which uses the U8903-109 BNC accessory kit. Methods for aligning such a matching attenuator and compensating for its loss are shown alongside the ease with which frequency response measurements can be made on the U8903B. 03 | Keysight | Measuring High Impedance Sources using the U8903B Audio Analyzer
