The Tektronix T5031 aka T503R is a Tek-made CRT used in the 561 and 567 scopes. It was the first Tek-made CRT with a rectangular faceplate.

The Tektronix T5032 is a successor with a minor difference – it was the first Tek-made CRT with internal graticule, totally eliminating parallax errors, and allowing for better edge illumination. This type is used in the 561, 567 and 568 oscilloscopes.

Ssuccessors of the T5032 are the T5610 (T561) and T5611 that had a ceramic envelope.
