The Tektronix 5031 is a dual-beam storage oscilloscope. There is a benchtop model, the 5031, and a rack-mount model, the R5031.
The channel-1 and channel-2 input attenuators use a rotary barrel cam that moves several small contact arms to select the desired path through the attenuator networks. The design is similar to that seen in several 7000-series plug-ins. The front-end amplifier starts with a differential amplifier formed by both halves of a 151-1027-00 dual JFET, Q46, followed by a dual PNP. The rest of the signal path comprises differential amplifiers made of discrete BJTs, including the deflection amplifier.
The 5031 has -4.1kV on the CRT cathode, and no post-deflection acceleration.
