Agilent 4291A - RF Impedance/Material Analyzer Product Overview HP 4291A impedance/material analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials. The 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 1 MHz to 1.8 GHz with 1 mHz resolution. A 1.8 m 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 fixtures and assure high accuracy and repeatability at DUT/MUT. The 4291A also provides automatic level control and monitor of test signals by using I-BASIC programming function; devices can be measured under a constant 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 (similar to 4194A's Equivalent Circuit Analysis Function.) The 4291A has two measurement channels; each channel can be set to measure a single (e.g., Z) or dual (e.g., Z-theta) impedance parameter. The color CRT with split-display can show both active traces and memory traces (stored in RAM). A built-in floppy disk drive stores programs and test data in either LIF or MS-DOS format. Key Features Basic accuracy ± 0.8% Advanced calibration and error compensation Four component test fixtures (DUT size: 0.5 mm to 20 mm) Independent parameter selection in 2 channels Direct read-out permittivity, permeability Two material fixtures (operating temperature: -55° to +200°C) Versatile analysis (temperature, cole-cole plot, relaxation time) Swept parameters (frequency, ac level, dc bias, temperature) Options / Remarks 001 - DC Bias Conditions In good condition.
