Cable BNC de 50 ohm[modifica]
La sortida del GF-232 és de 50 ohm. Això és important tenir-ho en compte alhora de posar-hi un cable BNC.
BNC connectors exist in 50 and 75 ohm versions, matched for use with cables of the same characteristic impedance. The 75 ohm types can sometimes be recognized by the reduced or absent dielectric in the mating ends. The 50 and 75 ohm connectors are typically specified for use at frequencies up to 4 and 2 GHz respectively.
