This section mainly showed the basic function and specification comparison between Saluki STB8851 and Wayne Kerr 6500B Impedance Analyzer.
Saluki STB8851 Series Precision Impedance Analyzer is a new generation impedance test instrument by adopting the current international advanced automatic balance bridge principle. It is based on Windows 10 operating system, which realizes a fully computerized operation interface, making the measurement more intelligent and easier. STB8851 series surpasses the 120MHz frequency bottleneck of similar instruments, achieving the measurement frequency from 10Hz to 130MHz.
Wayne Kerr 6500B Impedance Analyzer provides precise and fast testing of componenetsat frequencies up to 120MHz. It is a good choise for different tasks and applications including passive componenet design, dielectric material characterisation and manufacturing test.
