011-0058-00

The Tektronix 011-0058-00 (011-058) is a 93 Ω to 50 Ω, 0.5 W minimum-loss attenuator with BNC connectors.

If you look carefully at the male BNC connector (on the left end in each photo) note that you can see the white plastic insulator thru the bayonet slots in the BNC knurled "nut." This would be mostly covered by the slotted metal sleeve in a normal 50 Ω BNC, but was omitted here to reduce the capacitance for a 93 Ω connection.

See the 011-0042-00 for the 75 to 50 Ω version.
