Sharing few shots of this Tek vintage scope calibration tool that just received recently. Did a brief external inspection, it looks fine and well preserved. Powered up fine too, its just I haven't hook it to the scope to see it's output.
Planning to check it's signal and an internal inspection tear down to see what and how it look inside now, wishing no bad surprise, and hopefully I can manage to do it at this weekend, will post the innards photo shoots once its available.
This little thing is quite heavy for it's size.
Top front panel view, serial B031078 with few stickers overlapped with years printed on them, calibration date maybe ?
Front panel, with a date 1981 written at yellow sticker, probably that is the last traceable calibration date conducted. The main crystal oven led at the right side was on once its plugged at the mains, even the unit wasn't turned on. It blinked on and off periodically, looks like its maintaining the oven temperature, measured with kill-a-watt meter, while the unit was off, when that led was on, the oven it self consumes approx. 14 watt.
Rear panel, with switch and bnc for external reference clock.
Top and bottom view.
