1980's Cathode Ray Oscilloscope -- The EIectronics Inside 34

 

 

Most people will know an old tube TV, some will know tube oscilloscopes. But how many have seen the insides of a late 80s high quality scope? Will there be any surprises in this broken model?

  • Great tear down.

     

    Yes, the old Tektronix scopes were built to work in all kinds of environments.

     

    FYI, all CRT's emit a wide range of photons up to and including X-rays, some levels of gamma rays over a very wide spectrum.

     

    My first thought on the coil was a delay line. It was probably put around the CRT neck just for convenience.

     

    The encoder switches were cool to see. Hopefully you also noted the gold plated contacts for reliable contact.
