The paper presents the family of three analyzers allowing to measure impedance in range of 10 ohm<|Zx|<10 Gohm in a wide frequency range from 10 mHz up to 100 kHz. The most important features of the analyzers family are: miniaturization, low power consumption, low production cost, telemetric controlling and the use of impedance measurement method based on digital signal processing DSP. The miniaturization and other above mentioned features of the analyzers were obtained thanks to the use of the newest generation of large scale integration chips: e.g.. „system on a chip” microsystems (AD5933), 32-bit AVR32 family microcontrollers and specialized modules for wireless communication using ZigBee standard. When comparing metrological parameters, the developed instrumentation can equal portable analyzers offered by top worldwide manufacturers (Gamry, Ivium) but outperforms them on smaller dimensions, weight, a few times smaller price and a possibility to work in a distributed telemetric networks. All analyzer versions are able to put into medium-volume production.
