TASI Technical Software currently has software tools for the analysis of small signal piezoelectric properties, and large signal characterisation of piezoeoelectric, electrostrictive, ferroelectric, and antiferroelectric materials. Each software package is modular where extended features are supported through plug-in software modules. Each package also includes an optional data acquisition module allowing the collection of raw data directly from instrumentation.


PRAP

(Piezoelectric Resonance Analysis Program)

This software package allows the determination of complex elastic, piezoelectric, and dielectric properties of piezoelectric resonators. Included with analysis is the computation of components of Van Dyke's circuit model and those of a complex circuit model. An optional data acquisition module integrates the collection of resonance spectra from an impedance analyser.

This is a 32 bit Windows application that runs under Windows 95, 98, NT, 2000, ME, and XP. The Basic PRAP Package includes 7 standard one-dimensional resonance modes of 6mm (C¥) symmetry materials. Optional analysis modules add support for other crystal symmetries and resonance geometries. The Basic Data Acquisition Module includes drivers for a variety of impedance analysers and temperature controllers that allow direct acquisition of resonance spectra. PRAP has file formats for storing a single resonance spectrum and a compound file that stores a collection of spectra. Optional data acquisition modules allow a set of resonance spectra to be collected as a function of variables such as time, DC bias or temperature. These modules allow the study of such things as electrostrictive or ageing properties of piezeoelectric materials. A collection of resonance spectra in a compound file can also be used to compute the complete piezoelectric matrix of a material.


ZAP

(Impedance Analyser Program)

This software package incorporates all the features of the PRAP Basic Data Acquisition Module into a stand-alone application, allowing direct acquisition of resonance spectra from an impedance analyser. Beyond the graphical display of data, it does not include any of the analysis modules available with PRAP. This package should be of interest to those that are not interested in performing resonance analysis of electromechanical resonance spectra, but are interested in an simple automated way of collecting, viewing, and archiving the electrical properties (such as impedance or admittance) of a sample as a function of frequency.

This is a 32 bit Windows application that runs under Windows 95, 98, NT, 2000, ME, and XP. Included with the package is the Basic Data Acquisition Module of PRAP that includes drivers for a variety of impedance analysers and temperature controllers. This allows direct acquisition of sample impedance, admittance, etc. as a function of frequency. Optional data acquisition modules allow a set of impedance or admittance spectra to be collected as a function of time, DC bias, or temperature into a PRAP Compound File. Acquired spectra can be exported to ASCII text files or copied to the Windows clipboard to be pasted into other Windows applications. The data can be transformed into a variety of representations (such as impedance, admittance, etc.), and can be displayed in a Locus Plot.


STEP

(Electromechanical Response Characterisation Program)

This software package allows the large signal electromechanical characterisation of piezoelectric, electrostrictive, ferroelectric, and antiferroelectric materials. The name of the package refers to the four parameters of an electromechanical measurement;

       (S) Strain        (T) Stress        (E) Electric Field        (P) Polarisation or Electric Displacement

This is a 32 bit Windows application that runs under Windows 95, 98, NT, 2000, ME, and XP. The Basic STEP Package includes sets of large signal analysis models for piezoelectric, electrostrictive, ferroelectric, and antiferroelectric materials. Optional analysis modules add more specific and specialised models of analysis. The Basic Data Acquisition Module of STEP allows the electromechanical response of a sample to be measured using a variety of instruments. In principle, these measurements can be electric field-controlled, electric displacement-controlled, stress-controlled, or strain-controlled, depending on the instrumentation available. Additional optional data acquisition modules allow electromechanical response to be measured as a function of time, temperature, etc.
