Precision LC II Ferroelectric Tester

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.
