The ETB-168 is a comprehensive trainer designed to study the working of a Window Detector circuit using operational amplifiers (Op-Amps). This circuit is widely used in electronics for monitoring voltage levels within a specified range (window) and generating an output when the input signal lies within or outside the preset limits.
The trainer allows students to practically analyze the behavior of the circuit, understand upper and lower threshold settings, and visualize output response using a built-in digital meter. It comes equipped with a constant regulated (C.R.) power supply and safe test points for easy measurement.
Key Features:
Based on Op-Amp window comparator concept
Study of upper and lower voltage threshold detection
Built-in C.R. power supply and 1 digital meter
Well-labeled circuit layout and test terminals
Ideal for analog electronics, automation, and comparator applications labs
