011-0073-00
The Tektronix 011-0073-00 is an Input RC Standardizer with BNC connectors for calibrating instruments with 1 MΩ // 15 pF BNC inputs. It must be connected directly to the instrument input connector.
It was superseded by the 067-0537-00 Input RC Normalizer, which is identical except for the name and part number.
There does not appear to be an equivalent with UHF connectors.
