HP 4291A RF Impedance/Material Analyzer, 1MHz to 1.8GHz

Product Summary

The HP 4291A RF impedance /material analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials. The HP 4291A uses a direct current-voltage measurement technique, as opposed to 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 factors in fixture and assure high accuracy and repeatability at DUT/MUT.

The HP 4291A also provides automatic level control and monitor of test signals by using I-BASIC programming function; devices can be measured under aconstant voltage or current. Measure bias-dependent impedance characteristics with optional dc bias.(up to 40V and 100mA).

At the push of a button, the built-in Equivalent Circuit Analysis Function automatically calculates the circuit constant values of five circuit models.
