Wayne Kerr PAU3211A

The Wayne Kerr PAU3211A is a precision impedance analyzer engineered for accurate measurement of impedance parameters across electronic components and materials. Built for demanding R&D and quality control applications, it delivers the reliability and measurement precision required in laboratory and production environments.

– Technical Specifications

The PAU3211A measures a comprehensive set of impedance parameters: Inductance (L), Capacitance (C), Resistance (R), Dissipation Factor (D), Quality Factor (Q), Conductance (G), Impedance (Z), Admittance (Y), and Phase Angle (θ). DC resistance (Rdc) and transformer ratio measurement are also supported.

Equivalent circuit representation includes both Series and Parallel configurations. Series modes display C+R, C+D, C+Q, L+R, and L+Q combinations. Parallel modes provide C+G, B+G, and B+D options.

Operating frequency range extends to 300 kHz on the 3200 series. Drive level is programmable with 50Ω source impedance. Basic accuracy specifications vary across the product line, with select models achieving 0.02% accuracy.

– Key Features

• Programmable drive levels with 50Ω source impedance
• User-selectable measurement rates up to 20 measurements per second
• High-resolution color display with graphical interface and integral keypad
• DC bias capability via external bias units (individual units rated to 20A DC in 0.1A steps; multiple units can be paralleled for higher currents)
• Multiple interface options for data transfer and system integration

– Typical Applications

Component impedance characterization, material properties measurement, inductance analysis, and capacitance evaluation in laboratory research and quality assurance testing.

– Compatibility & Integration

The PAU3211A supports GPIB (IEEE 488), Parallel I/O, and RS232C Serial data output ports. Handler interfaces are available for automated test systems. DC bias units including the 3220 series and 3265B Series can extend functionality for biased measurement applications.
