| The 661 Vertical Test Load Unit is a plug-in for testing
| | #redirect[[067-0066-00]] |
| the power supplies and interconnections in a Tektronix [[661]] sampling scope.
| |
| It serves a similar purpose to the [[TU-4]] (for the 560-series) and [[1M1]] (for the 500-series).
| |
| It contains load resistors for testing the mainframe's power supply.
| |
| It also contains 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.
