"The Tek 017-071 is an adapter for use with the Tektronix 519.

It was shipped as a standard accessory with the 519 1 GHz oscilloscope that had 125 Ω input impedance."


there are some of each, so choose the quantity and type you want from the dropdown list - choose by part number to get the ones you want. discount, and you save shipping if you get more than one at the same time.  I will be listing some more adapters and attenuators for this scope soon.
