Impedance Measurement
CITS880s
-
Finer geometries and thinner copper can present a challenge for fabricators measuring impedance on leading edge PCBs. The CITS880s answers that challenge with the introduction of Launch Point Extrapolation (LPE). LPE extrapolates the TDR response back to a point close to the start of the transmission line effectively allowing to users more accurately to measure the instantaneous or incident impedance of the line.

Electrochemical Impedance Spectroscopy (EIS)
-
Electrochemical impedance spectroscopy (EIS) is a method for the non-destructive characterisiation of thin layers, membranes, surfaces and films. Typically a small amplitude AC voltage (or current) signal is applied to a sample while the amplitude and phase relationship of the corresponding current (or voltage) signal is monitored.

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.

ST2839
-
ST2839 series precision impedance analyzer is a new generation impedance test instrument by adopting the current international advanced automatic balance bridge principle. Its basic accuracy of 0.05%, the fastest test speed of 5.6ms, the frequency range of 20Hz-10MHz, and the impedance test range of up to 1GΩ can meet the testing requirements of components and materials, especially for low-loss (D) capacitors and high-quality Measurement of Factor (Q) Inductors. The four-terminal pair port configuration method can effectively eliminate the influence of the electromagnetic coupling of the test line, and expand the lower limit of the low-impedance test capability ten times lower than that of the conventional five-terminal configuration instrument.
