The ETB-217 is a comprehensive training system designed for the in-depth study of key parameters of an Operational Amplifier (Op-Amp), including input-bias current, output-offset voltage, and slew rate. It is an ideal tool for electronics and instrumentation engineering students to understand and measure the performance metrics of Op-Amps in real time.

Equipped with a built-in regulated power supply, clearly labeled circuit sections, and standard Op-Amp ICs (such as UA741), the trainer simplifies experimental setup and measurement. It provides dedicated terminals and measurement points to accurately observe and calculate the required parameters using external meters or oscilloscopes.

Key Features:

• Measurement of:

  • Input Bias Current

  • Output Offset Voltage

  • Slew Rate

• Built-in ±12V regulated power supply

• Uses standard Op-Amp (e.g., UA741)

• Onboard passive components and accessible test points

• Educational-grade layout with circuit diagram printed on the board

• Compact and durable design for lab use

Applications in Learning:

• Deep understanding of Op-Amp internal behavior

• Practical knowledge for analog design and troubleshooting

• Foundation for precision analog electronics and instrumentation
