Picotest J2200A Optocoupler CTR Measurement Kit

Overview

The Picotest J2200A Optocoupler CTR Measurement Kit is an indispensable tool for professional design engineers seeking precision in their circuit design. This kit simplifies the measurement of key parameters such as Current Transfer Ratio (CTR), ΔCTR, V_F, and ΔRd for optocouplers. It supports various bias conditions and offers pulse current mode measurement to reduce temperature rise during testing, thereby improving measurement accuracy.

Optocouplers, crucial for isolation feedback control circuits, have varying CTR ranks from 50% to 600%. The J2200A kit can measure both AC and DC parameters, which is not typically provided by manufacturers. This feature is essential for engineers to select and design the appropriate optocouplers under real application conditions. The kit includes the M3522A Digital Multimeter (DMM), ensuring all necessary capabilities for quick and accurate measurements are readily available.

With the rise of counterfeit optocouplers in the market, the J2200A is an excellent tool for incoming quality control (IQC), allowing engineers to identify genuine components. Its versatility makes it suitable for multiple applications, including:
