designed for testing of the fuel cell with the small current (5 A or less), and not only the current-voltage characteristic test, the KFM2005 can easily measure for the impedance of a fuel cell using the AC impedance method, and the Cole-Cole plot. Using the measurement data of the Cole-cole plot, it is possible to calculate the circuit constant of the approximate equivalent circuit of the fuel cell. The built-in DC load (60W) is capable to operate from 0 V, and it can perform the test for the fuel cell up to 20V and 5A.

Manual Tuners / Impedance Tuners
-
Maury manual tuners are based on precision slide screw technology that utilizes broadband slab line transmission structure and passive probes to create impedances for devices. The probes are designed to be very close to onequarter wavelength in the linear dimension at the mid-band of each range. Since each tuner has two probes, this results in improved matching characteristics for each unit. Another key feature of this series of tuners is the inclusion of a LCD position readout of the carriage position on those units operating below 18 GHz. Higher frequency tuners utilize a micrometer carriage drive. The positional repeatability and high matching range of these tuners make them ideally suited for use as a variable impedance source in applications like device characterization. Such measurements depend upon the ability of the tuner to establish impedances out near the edge of the Smith chart and to reproduce the electrical characteristics as a function of mechanical position. The tuners in this series are also easy to use due to the nearly independent electrical results of the mechanical motions. The depth of penetration of the probe into the transmission line determines the magnitude of the reflection, while the position of the probe along the line determines the phase. While there is some interaction, the effects are almost independent of each other. https://www.maurymw.com/images/mw-rf/mst982e35.jpg

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.
