![]() After preamplification, the two channels meet at an electronic switch. Therefore the amplitude of each input, as viewed on the oscilloscope, can be individually controlled. ![]() There are two separate vertical input channels, A and B, and these use separate attenuator and preamplifier stages. The figure below shows the construction & working dual trace oscilloscope. Here we are going to discuss dual trace oscilloscope whose working and construction is completely different from dual beam oscilloscope. Two input oscilloscopes are described, dual trace and dual beam. Single beam which can then be converted into several traces, and dual beam, which may also be converted into a further number of traces. Two inputs are the most common, although four and eight inputs are available for special application. ![]() Oscilloscopes can have multiple inputs and display facilities. ![]() Dual Trace Oscilloscope Working Principle: ![]()
