概要（Overview）

The HP 4291B RF impedance/material analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials. The HP 4291B uses a direct current voltage measurement technique, opposing the reflection measurement technique, for more accurate impedance measurement over wide impedance range.Basic impedance accuracy is ± 0.8 % . High Q accuracy enables low-loss component analysis. An internal synthesizer sweeps frequency from 1 MHz to 1.8 G Hz with 1 mHz resolution. A 1.8 -m error-less cable connects the analyzer to a test station so you can ex tend your test point away from the analyzer without losing accuracy. Advanced calibration and error compensation function eliminate measurement error factors in fixtures and assure high accuracy and repeatability at DUT/MUT.
