The 4291A RF Impedance / Material Analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials. The unit 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 1MHz to 1.8GHz with 1MHz resolution. A 1.8m error-less cable connects the analyzer to a test station so you can extend your test point away from the analyzer without losing accuracy. Advanced calibration and error compensation function eliminate measurement error factorsw in fixtures and assure high accuracy and repeatability at DUT/MUT.
