Connectors
Tektronix equipment makes use of a wide variety of connectors. Most of the connectors were standard parts when the instruments were designed. Occasionally custom connectors were designed. What follows is a partial list of connectors used in Tektronix equipment.
BNC
BNC is the most common connector for measurement equipment up to 1GHz. It is available in different impedances. 50-ohm is the most common. Tektronix gear transitioned from UHF connectors to BNC connectors in the early 1960's. For some pieces of equipment, a conversion kit was available.
SMA
SMA connectors are good to about 20GHz. The male connectors have a protruding center pin and ground shroud that screws on. They are similar to UHF connectors, but much smaller and with much tighter tolerances and better controlled impedance. The female is threaded on the outside.
