Solutions for Measuring Permittivity and Permeability Application Note 1297 Meeting Tomorrow's Material Test Challenges Solutions For Your Application Selecting the Best Solution Performance of base materials has a fundamental impact on the success of your end-product Whether you are looking for simple measurement hardware for QA, or need a sophisticated package with fixtures, instrument- ation, and software to improve your design, HP has the right tools for you. For testing bulk materials you need fixtures, precise instru- mentation, and perhaps software to analyze and output your test data in an user-definable format. Fixtures are a vital link that allow an instrument to connect from the front panel to the material under test. Fixturing is never easy; your sample may be freezing cold or boiling hot, liquid or solid, thick or thin. Your testing could be at low frequencies, at millimeterwave, or somewhere in between. And so, you have to pick the right fixture for the right physical and electrical test conditions. Instruments perform the actual material measurements using a number of techniques. LCR meters are an excellent choice when your application requires a low Application/Test Requirement frequency test at discrete points. Impedance analyzers have the benefits of extended frequency range, a synthesized source, and swept measurement capability. Network analyzers are the best solution for swept high frequency measurements. The information on this page will assist you in understanding HP's wide range of test fixtures, versus frequency.
