The Tektronix 211 is a 500kHz single-channel miniaturized analog battery-powered oscilloscope.
The probe input first goes through compensated attenuators and then into one gate of Q18, a dual JFET. The drains of the dual JFET drive the inputs of an amplifier IC, U25, part number 155-0057-00.
Triggering is done using a 155-0048-01.
The 211 uses a 155-0047-00 for X and Y amplification until the final stages, which use NPN transistors to drive the CRT deflection plates.
