The Tektronix 517 is a 50MHz scope introduced in 1950 or 1951. The power supply is an external box, like the 507, 551 and 555. The 517 does not take plug-ins. There is also a 517A. The 517 closely resembles a scope that Tektronix developed under a contract for the US military during 1949 and 1950.

The external power supply and oscilloscope are connected by a removable cable with Jones plugs on both ends. Units with serial numbers 101-1739 use a 12-pin Jones connectors; after that it is a 16-pin Jones connector. The voltages on the 12-pin connector are:

  • Pin 1: +750V, regulated
  • Pin 2: +475V, regulated
  • Pin 3: +350V, unregulated
  • Pin 4: +225V, regulated
  • Pin 5: +150V, regulated
  • Pin 6: Ground
  • Pin 7: -250V, regulated
  • Pin 8: +180V, unregulated
