List of some oscilloscope switches :

(A) The screen : It is made up of tiles measuring 1 cm on each side.

(B) The main axes.

(1) On/Off : Oscilloscope on and off button.

(2) Controls the vertical position of the signal.

(3) Voltage gauge : this switch is used to change the vertical scale. The unit is V/cm,  mV/cm,  µV/cm.

(4) AC/DC : This switch allows you to adjust the direct current signal (DC, Direct Current) and the alternating current signal (AC, Alternating Current).

(5) GND : It allows the plates to be connected to ground. It also allows you to adjust the level 0V.

(6) Entry port for channel 1.

(7) Entry port for channel 2.

(8) The mode : The majority of oscilloscopes have a dual input, which means that two signals can be viewed at the same time.

(9) Activate the Lissajous curve by pressing the button and choosing the mode CH2 (switch 8).

(10) Time caliber : This switch is used to change the horizontal scale. The unit is s/cm,  ms/cm,  µs/cm.

(11) Trigger level : For the device to be able to display a signal, it must define an input voltage level from which it will start displaying.

(12) Trigger source : The device must observe signals that repeat periodically. The oscilloscope must start at the same point on the wave function to have a stable image. There are two modes : norm et auto (you have to leave it on auto).
