Precision LC II Ferroelectric Tester


Precision LCII Ferroelectric Test System


The Precision LCII is Radiant's answer to a growing need for affordable characterization equipment.  The Precision LCII is an ideal general-purpose tester with a broad test range for thin films and bulk ceramics.  The Precision LCII tester has a frequency rating of 5KHz at +/-200V built-in to the system.   Using up to 32,000 points with18-bit resolution from 2kHz out to 1/30th of a Hertz for capacitors ranging from square microns to square centimeters, the LC II enables high resolution characterization for bulk capacitors. The Precision LCII II is offered with a variety of internal amplifiers.  The Precision LCII is offered in a ±10V, 30V, 100V, 200V, and 500V built-in drive volt option.  The Precision LCII can be expanded to 10kV with the addition of a high voltage interface and amplifier. 

 Includes Vision Data Acquisition and Management System Software.

– A Library of 155 measurement, analysis, plotting, program control, and documentation tasks.

– An Editor to arrange multiple tasks together from the Library into a Test Definition.

– An Execution Engine to read and execute the Test Definition

– An amorphous database engine to Archive everything that happens in each Test Definition.


The Precision LCII executes hysteresis, pulse, leakage, IV, and CV (and many other tasks) measurements without changing sample connections.  With the addition of extra fixtures, the Precision LCII can measure pyroelectric properties, magnetoelectric properties, transistor characteristics, cryogenic properties, bulk and/or thin film piezoelectric properties.  

Vision dramatically increases the productivity of the researcher, reducing the time required to acquire data in an experiment.  Vision’s enhanced productivity directly reduces cost of test.  Vision dramatically increases the complexity of the research that may be accomplished by allowing researchers to combine different measurement tasks with environmental controls into an automated test procedure managed by programmable logic embedded with automated data collection, analysis and plotting tools. 

Materials Testers running under the Vision Materials RDP Operating System reduces Cost of Test by a factor greater than 10 over any other ferroelectric tester
