The Tektronix 211 is a 500kHz single-channel miniaturized analog battery-powered oscilloscope. | 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. | |||
