DESCRIPTION
The 4291B RF impedance/material analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials. The 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 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 eliminates measurement error factors in fixtures and assures high accuracy and repeatability at DUT/MUT.

The 4291B 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 TFT 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. With built-in IBASIC, you can control external test equipment such as a temperature chamber or wafer prober directly from the 4291B. You do not need a separate instrument controller.

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 (option)
• Two material fixtures (operating temperature: -55deg C to +200deg C)
• Versatile analysis (temperature, cole-cole plot, relaxation time)
• Sweep parameters (frequency, ac level, dc bias, temperature)
