CEDIA ESPA EST Practice Test

Answer - C - You should have a resistance level of 75 Ohms on a video system for impedance and termination.

Key Takeaway: If coaxial cabling is used to connect a video camera to a video integration or encoding device or to the network through a video balun, the resistance level should be 75 ohms. The 75 ohms is for both impedance and termination. Impedance is the resistance and reactance on the cable. Termination absorbs the 75-ohm signals at the terminal device and prevents signal overload.
