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.
SMB
SMB connectors are small snap-on RF connectors developed in the 1960's. They come in 50-ohm and 75-ohm variants. Their RF performance in somewhat inferior to SMA connectors, but they are more compact and have the convenience of being snap-on instead of having a screw-on grounding nut.
GR-874
Peltola
The Tektronix website says the following about Peltola connectors:
The Peltola connector was developed for in-house use by Tektronix (and developed by Ron Peltola). However, the pieces to make the connector are these:
The Male coaxial connector consists of the RG-174 coax center conductor as the male pin, with the braided shield pressed between two eyelets, part number 210-0775-00 (smaller one) and part number 210-0774-00 (larger one). The outer eyelet is then "dimpled" to secure the eyelet-shield-eyelet combination.
The Female (circuit board mounted) connector consists of 2 pieces. In the center is the socket pin connector, part number 136-0252-07 and the connector recepticle (with 3 circuit board mounting tabs), part number 131-1003-00.

BSM
Several Tektronix products use BSM connectors, such as the 7T11, 11B2, 3S2, S-50. S-51, and S-52. These look like minature BNC connectors. They are much less common than BNC connectors. There are two-lug variants and three-lug variants. Tektronix used the two-lug variant. They are also sometimes called MB connectors. The 067-0587-01 uses one for TRIG OUT.
