What is the termination/dummy load?
Termination/dummy load is a resistive component that absorbs all the output power of an electrical generator or radio transmitter in order to simulate working conditionsfor test purposes.
The function of termination/dummy load
A. To test a radio transmitter ,it acts as a protector to be a substitute of antenna.50ohm dummy load provides proper resitance at final RF amplifier stage.
B. To prevent away from other radios interference when ajusting and testing the transmmiter
C. To be a replacement of the loudspeaker during audio amplifier testing.
D. To be used in the isolated port in a directional coupler and the unusedport of a power divider.
