Measuring High Impedance Sources
Using the U8903B Audio Analyzer
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
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.
