AgilentLCR Meters, Impedance Analyzersand Test FixturesSelection GuideComponent and Material Measurement Solutions
Cost Effective Solutions for Your ApplicationsWhether your application is in R&D, production, qualityassurance, or incoming inspection, Agilent Technologieshas the right impedance measurement solution for you.Agilent has a complete line of impedance test equipmentand test accessories to help you task efficiently. Whenyou choose an impedance measurement product fromAgilent, you get more than accurate and reliable testresults. Agilent offers:Advanced measurement techniquesfor a wide range of applicationsComplete solution: Covering frequencies from 20 Hzto 3 GHz, Agilent's impedance product line offers youthe widest selection of equipment for your application.In addition, several third-party companies have complementary products designed to work with Agilent equipmentfor special applications. This brochure gives an overviewof all the products you can choose from. Auto-balancing bridge offers widest impedancemeasurement range with typical frequency rangeof 20 Hz to 110 MHz. This technique is best forlow-frequency, general-purpose testing.Convenience: Any time you have an impedance measurement need, help is only one phone call away. Agilent offersthree types of impedance measurement solutions as shownin Table 1. Calling Agilent will put you in contact withone of our trained engineers to help you find a solution.Agilent's impedance product measuremanttechnique comparison 10% accuracy range100MImpedance measurement range (ohms)Knowledge: Agilent has decades of experience providingimpedance measurement solutions. Years of experienceand continuing technical innovations go into the designand manufacturing of each Agilent LCR meter andimpedance analyzer. Agilent also has a list of technicalpublication to assist you in many different applications(see page 15 for full listing.)Figure 1 is a comparison of different measurementtechniques used in Agilent's LCR meter and impedanceanalyzers.

I-V technique covers from 40 Hz to 110 MHz with a morefocused impedance measurement range. I-V techniquealso allows probing for in-circuit testing. RF I-V, an enhancement of the I-V technique, offerssome of the high-frequency benefit of network analysiswhile retaining some of the impedance measurementrange of the I-V technique. Designed for accuracy andhigh-frequency performance, the RF I-V technique isexcellent for RF component analysis, especially forsmall inductance and capacitance values.How to use this selection guideTable 2 is a summary of all of Agilent's impedanceproducts. It is designed to assist you in better comparingAgilent's wide range of instrumentation and in choosingpossible solutions for your applications, depending onyour requirements in the following areas: Test frequency range Device type or application type Accuracy requirement (measurement technique) Network analysis offers the highest frequency coverage,but works best when the measurement range is closeto 50 Ω. With this measurement technique, impedancevalues are derived from reflection coefficients. Networkanalysis is most widely used for RF and mic
