Inputs And Vertical Controls II




A dual trace oscilloscope can also be used as an oscilloscope simple trace. A selector switch allows you to select each channel individually or both simultaneously. This switch has at least three positions: CH1, CH2 and DUAL.

In the CH1 position appears only the image screen that is applied in vertical inlet channel 1.
In the CH2 position appears only the screen image that is applied in vertical input channel 2.
In the DUAL position the two images appear.

In more sophisticated oscilloscopes, this switch can have more positions to allow other alternative uses.
