067-0609-00
The Tektronix 067-0609-00 is a Common Mode Rejection tester for 7000-series scopes. Used in conjunction with the 067-0587-00 Signal Standardizer Fixture to determine the CMRR of 7000-Series Mainframe Vertical Interface Amplifiers. The 067-0609-00 CMR Checker plugs into both mainframe Vertical connectors at the same time. It accepts the 067-0587-00 Signal Standardizer through the left Vertical compartment of the mainframe. The 067-0609-00 routes the CW signal from the 067-0587-00 to both main-frame Vertical inputs, maintaining 50 ohm terminations to the Signal Standardizer. Precision-length coax-ial cables introduce time delay to equalize arrival time of waveforms to each Vertical connector.
