TEKTRONIX 7903 MAINFRAME 500 MHz OSCILLOSCOPE This is a 3 slot 500 MHz mainframe from Tek. It can take many plug-ins, up to 4 channels. We have some plug-ins to list in the future, so if you need Tek 7000 series plug-ins, please check our other listings in the near future. It's controls are pretty simple, one interesting area is the 4 level Calibration output which is at 50 Ohms. This scope is used & has a few scratches & scrapes on the outer case. The front is in good shape. I tried testing this scope. It does not power up. Both fuses are good. When testing items, I plug them into my Heathkit AC Power Supply. It has a current meter so I can see how much current an item being tested draws. This scope makes a quick peak current & drops to 0. This indicates that the big filter caps are charging, but the power supply's oscillator isn't starting up. If you have a schematic for this scope, you can probably fix it easily.
