See 50 Ohm RF Termination
Bokep
- In RF circuits, a termination is a device that is used to match the impedance of a transmission line to the characteristic impedance of the load. The impedance of the termination should be within 0.5 Ω of 50 Ω, even at many GHz1. A termination will have a specification for return loss, which is the reflection it produces in a 50 Ω system, and the frequency range this is valid for1. A cheap termination will be say 20 dB return loss from DC up to 1 GHz1. If the signal generator is terminated with a 50 ohms load, the measured voltage across the load is 50/ (50+50) (2 Display)=Display2.Learn more:✕This summary was generated using AI based on multiple online sources.

If connected to a high impedance load you get 2 Display Volts at the output, which is twice the voltage seen on the display.electronics.stackexchange.com/questions/550000/…
