This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Dual Trace Oscilloscope.Dual Trace Oscilloscope has two channels A and B which are passed through different preamplifiers and attenuators, the input stage circuit has a diode that prevents damage to FET Transistors that produces more negative input difference Next, is a resistor network which prevents the input stage from high positive voltage swings. For channel switching electronic switch logic and the flip flop is used. Two modes of operation take place in DTO.One mode is the Alternate method and the other mode is a Chopped method. A triggering circuit is used to provide trigger pulses to multivibrators. Time base generator operates on the current integration principle. DTO has a deflection accuracy of 5%, the voltage range is 220v, the frequency is 50hz, and the maximum temperature is 5-40 degrees C. Advantages of DTO are that two independent signals are observed on the CRT screen.Applications of Dual trace oscilloscopes are used in function generators, and to visualize the intensity levels of the source signal.1).
