Tektronix 1503B

Описание: Workshop Project #36 - Tektronix 1503B TDR

This one took quite a while to complete. Why would I need one of these? Well, getting into some radio stuff more and more recently, I thought it might be good to make sure any antenna cable is halfway decent at least. This unit seems to be still in use by several hobbyists at least, and there's quite a bit of modding info out there. The LCD display is a known failure point, especially the EL backlight. In this video, I do the usual cleanup and repair of the device, so that it does provide proper measurements again.
