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 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.

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
