Residual attenuation is the minimum attenuation of a variable Attenuator.
Residual attenuation is the minimum attenuation of a variable Attenuator. Standard ToolBook II field. It was stated earlier that the difference between power into a device and the power out of that device is the attenuation of the device. If there is a mismatch, there will also be some power reflected. The total of power reflected and power attenuated is called insertion loss.
