Specifications

The following topics comprise a helpful guideline for selecting an appropriate accessory for the measure-
ment instrument to be used.
1. Selection by Measurement Application
Agilent accessories can be used in a wide variety of measurement applications. These applications range
from basic measurements (such as impedance measurements for discrete devices) to advanced measure-
ments (such as measurement of resistivities or dielectric constants.)
2. Compatibility with Measurement Instruments
Test fixtures/leads are compatible with the measurement instruments when they have the same type of
terminal configuration and useable measurement frequency range. The measurement instruments
described in this guide are divided into the following four categories based on frequency.
