An Ideal General Purpose, Affordable Tester

DSC 3461(1)

The Precision LCII is Radiant's answer to a growing need for affordable characterization equipment. It is an ideal general-purpose tester with a broad test range for thin films and bulk ceramics, with 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.

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 Data Acquisition & Management System Software Included

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.

  • 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.

Radiant’s Precision Line of Test Systems are driven by Vision Software. Vision is a revolutionary software package that provides exceptional freedom to design, conduct, and review all procedures associated with any material experiment. The Vision test environment will collect all data acquired in a test sequence and organize it in archived data structures along with the test sequence definitions and data analysis tools. The experiment can always be recalled or reproduced. Data and test conditions can be shared over the Internet to allow collaborative research.

Measurements include, but are not limited to - Hysteresis, Leakage, Charge, Retain, Resist, I/V, Fatigue, C(V), PUND, Imprint, Leakage Current, Remnant Hysteresis, Small signal CV, imprint, retention, and piezoelectric displacement from one hardware configuration. Radiant offers optional Piezoelectric, Magnetoelectric, Transistor, and Pyroelectric software programs
