Description
Delivery scope

Applications and Experiments:_..

The following topics are covered:_..
•	Investigating the deflection of an electron beam in an electric field
•	Investigating the deflection of an electron beam in a magnetic field
•	Demonstrating the display of signals on an oscilloscope, using the periodic signal from a function generator
•	Calibrating the frequency controller of the sawtooth generator

Experiment Description:_..

The training oscilloscope is used to study the physical principles of the time-resolved display of electrical signals on a fluorescent screen. In a didactically modified Braun tube, a focused electron beam is generated, and its point of impact on the fluorescent screen is visible as a green luminous spot. When the electron beam is deflected by a sawtooth voltage applied between a pair of deflector plates, it moves at a constant speed from left to right across the screen and then returns to the starting point. This process is repeated cyclically at an adjustable frequency. The time-dependent voltage to be displayed is applied to a coil located outside the tube, causing the beam to be deflected vertically in the magnetic field of the coil. The time dependence of the signal is resolved by the simultaneous horizontal motion of the electron beam and displayed on the fluorescent screen.
