Features: The Operational Amplifier Tester efficiently distinguishes high speed and low speed op through double frequency waveform analysis (200kHz/10Hz), featuring LED indicators for real time verification. Built with terminals for power supply current measurement, this plastic tester enable detailed characterization of amplifier currents and model differentiation. Ideal for electronics engineers, and circuit designers requiring component validation in prototyping, repair, or manufacturing environments. Perfect for laboratory testing, production line quality checks, and educational workshops analyzing operational amplifier response characteristics under varied frequency conditions. This double power supply tester simplifies amplifier with plug and play functionality, combining robust plastic construction with clear visual through synchronized LED indicators.
