Description

Overview

GAOTek digital bridges LCR generators are high-precision component parameter analyzers that make use of the automatic balancing bridge principle. They feature a testing bandwidth of 10 Hz to 1 MHz, continuously adjustable frequencies, 0.05% of basic measuring accuracy, automatic level control, list scanning, and position counting. These generators can provide accurate and comprehensive measurements and analyses for most components and materials, so they are widely used in product R&D, component incoming inspections, and online product sorting.
