Description of E4990A Impedance AnalyzerThe E4990A impedance analyzer has a frequency range of 20 Hz to 120 MHz, providing excellent basic accuracy of 0.045% (typical value) over a wide impedance range. It also includes a built-in 40 V DC bias source. The equivalent circuit analysis function supports 7 different multi-parameter models, which can assist you in simulating the equivalent parameter values of components.Five frequency options (20 Hz to 10/20/30/50/120 MHz) and frequency upgrade options allow you to choose more suitable options based on your current investment.With the speed-up measurement option (option 001), the low-frequency model of the E4990A (10M/20M/30M/50M) now has a speed comparable to the flagship product, the 120 MHz E4990A. It enables engineers to precisely evaluate components such as resonators or inductors, or conduct precise quality inspections (which require multiple-point measurements of each component or measurements of multiple tested components), thereby reducing overall testing costs.The E4990A supports a variety of test accessories, making the measurement simple and reliable.Whether you are engaged in research and development, quality assurance, or quality inspection work, the E4990A can help you accurately characterize and test electronic components, semiconductor devices, and materials. In terms of material measurement, when combined with the E4990A and N1500A-005/006 material measurement kits, the entire measurement process from setting up the fixture to generating the report can be completed very easily.
