This is called a "dual trace" oscilloscope. The switch worked to display 2 or 4 separate electrical signals on the screen. This required little duplication and added only a small amount to the cost. This is the technique used in all the dual and four-trace plug-ins such as the CA, 1A1, 1A2, Type M and 1A4.
Dual-trace controls green trace = y = 30 sin(0.1t) + 0.5 teal trace = y = 30 sin(0.3t) Each input channel usually has its own set of sensitivity, coupling, and position controls, though some four-trace oscilloscopes have only minimal controls for their third and fourth channels.
A dual-beam oscilloscope was a type of oscilloscope once used to compare one signal with another. There were two beams produced in a special type of CRT . Unlike an ordinary "dual-trace" oscilloscope (which time-shared a single electron beam, thus losing about 50% of each signal), a dual-beam oscilloscope simultaneously produced two separate ...

Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
This so-called I–V (current versus voltage) data is either directly displayed on an oscilloscope screen, or recorded to a data file for later processing and graphing with a computer. [1] Configuration includes the maximum voltage applied, the polarity of the voltage applied (including the automatic application of both positive and negative ...
A Tektronix TDS210 digital oscilloscope. A digital storage oscilloscope (DSO) is an oscilloscope which stores and analyses the input signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides. [1]
A theorem which states that any network of current sources, voltage sources and resistors can be simplified to an equivalent network with only a voltage source and series impedance; the dual of Norton's Theorem. third rail An energized conductor in the track bed, using a sliding contact to transfer power to an electric train.
