The Tektronix 067-0066-00 is a pair of calibration fixtures for the 661 oscilloscope, one "Sweep Test Load Unit" and one "Vertical Test Load Unit".

The Vertical Test Load Unit serves a similar purpose to the TU-4 (for the 560-series) and 1M1 (for the 500-series), for testing the power supplies and interconnections.

It contains load resistors for testing the mainframe's power supply, as well as a switch for testing the wiring between the plug-in interface and the multi-pin digital output connector on the rear of the 661 mainframe. There is a banana connector on the front of the plug-in that is wired to the +300 V pin on the interface connector via a fuse.

The Sweep Test Load Unit has a UHF connector for an external 150 V sawtooth signal to check the sweep. please expand
