Signal generator is an electronic instrument that can generate various frequency, amplitude and waveform signals. It can be used to test the performance of electronic equipment, communication systems, audio systems and other fields. High resistance and low resistance are two states of the output impedance of the signal generator, which will affect the signal transmission and measurement. In the signal generator, the setting of high resistance and low resistance is usually realized by adjusting the impedance matching of the output port. Specifically, the high resistance output means that the output port of the AOZ1212AI signal generator has a high resistance value and is close to the open circuit state. At this time, the current output by the signal source is very low and the voltage is high. The low resistance output is just the opposite. The output terminal of the signal generator

Hall effect is an electromagnetic effect, which was discovered by Edwin Herbert Hall in 1879. When the current passes through a thin layer of conductor, there will be a voltage difference at the edge of the conductor perpendicular to the current direction. This phenomenon is the AD6458ARS Hall effect. The voltage generated by Hall effect is called Hall potential. The essence of Hall effect is that when a carrier in a solid material moves in an external magnetic field, its trajectory will shift due to the action of Lorentz force, and the charge accumulation will occur on both sides of the material, forming a charge perpendicular to the electricity
