High Impedance Transformers
Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.

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

Battery Impedance Meter
Operation is fast and simple. Just press the spring-loaded probes onto the two poles of the battery. After 1.5 seconds, the unit beeps (indicating good contact) and displays the battery voltage and either the number of siemens or milliohms, depending on the knob setting. The display continues to show these numbers after the probes are removed; it resets only when the probes are pressed onto the next battery. The impedance and voltage of any battery between 1.2 and 60 volts can be read. Because of the wide range of voltages, even single low-voltage cells, such as NiMH, can be measured. The manufacturers of some batteries specify impedance in milliohms while other specify in siemens (one divided by the resistance in ohms). This meter will display both types of impedance for any given battery. Accuracy is +/- 2% of the value.

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.

Localized Electrochemical Impedance Spectroscopy
VS-LEIS
The VersaSTAT 3F applies an AC voltage to the sample emerged in electrolyte. This "global" voltage generates AC current to flow at the electrode / electrolyte interface. A dual-element probe is positioned in solution close to the surface of the sample. The electrometer measures a differential voltage measure between the two measurement elements as a measure of local voltage-drop in solution. This voltage-drop exists in solution because of current flow from local reactions at the sample, the resistance of the electrolyte and the spatial separation of the dual measurement elements.
