Eichgenerator (für Oszilloskop)

A linear timebase and stable trigger circuits are essential to the operation of an oscilloscope. Good linearity of the timebase ensures that there is no distortion of the displayed waveform along the X-axis, while stable triggering ensures a jitter-free display. In this month`s article the circuits of the time- base, trigger circuit, X and Y amplifiers, channel switches and Y-preamps are discussed.
