Automated Tuners / Impedance Tuners / Load Pull Tuners
MT97x, MT98x and XT98x series automated tuners (also known as automated impedance tuners and automated load pull tuners) are precision instruments that are optimized for a broad class of in-fixture and on-wafer applications, and may be used in any automated or manual application requiring the ability to match the impedance of a microwave circuit element or to establish specific impedances at a terminal interface. The tuner design is based on the slide screw concept using the inherently broadband slab-line transmission structure. Each unit has two non-contacting probes deliver high VSWR with superb accuracy and reliability over a wide frequency range. These probes can be fully retracted leaving a low-loss, well-matched transmission line, which is a significant benefit in power related applications where two-port tuners capable of handling large amounts of power are required. As integral components of Maury Device Characterization Solutions, these PC-based tuners are controlled using Maury's family of Device Characterization Software tools, including MT930 IVCAD, MT993 ATS and the DLL-based measurement automation environment. Maury Microwave automed impedance tuners are ideal for load pull, harmonic load pull, active load pull, hybrid active load pull, noise figure, noise parameters and all automated tuner applications.

Impedance Analyzers
A/D converted input signals undergo discrete Fourier transform (DFT) to calculate complex impedance values and obtain parameters and characteristics specific to the DUT, such as its capacitance, inductance and quality factor. Original NF algorithms are also applied to allow equivalent circuits made up of R, L and C along with the constants for those circuits to be estimated from the complex impedance spectrum obtained by sweeping the frequencies.

Impedance Meter, Audio, 200Ω, 2KΩ and 20KΩ scales
72-6948
Active device is essential for reliable installation of background music and paging systems in residences, offices buildings and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior to operation. Unlike conventional volt/ohm meters, which measure DC resistance, this unit utilizes an internal 1KHz oscillator to measure true impedance. Accurately measure speaker lines that utilize impedance matching volume controls, switchers, transformers and passive crossovers. Because this unit accurately measures up to 20Kohm, it may also be utilized with 25V, 50V, 70V, and 100V speaker line transformers in commercial installations.
