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 oscilloscopes have a mode switch to select either channel alone, both channels, or (in some) an X‑Y display, which uses the second channel for X deflection. When both channels are displayed, the type of channel switching can be selected on some oscilloscopes; on others, the type depends upon timebase setting.
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 ...

1947 Heathkit ad featuring the 5-inch oscilloscope. Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $335 in 2023) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath ...
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]
These modules switch the power using an impulse relay. In the U.S., these modules are generally rated to control loads up to 15 amperes (1800 watts at 120 V). Many device modules offer a feature called local control. If the module is switched off, operating the power switch on the lamp or appliance will cause the module to turn on.
A passive oscilloscope probe with a switch in the probe handle that selects 1× or 10× attenuation To minimize loading, attenuator probes (e.g., 10× probes) are used. A typical probe uses a 9 megohm series resistor shunted by a low-value capacitor to make an RC compensated divider with the cable capacitance and scope input.
