Vertical Deflection Amplifier

Return to Main Oscilloscope Page

The vertical deflection amplifier uses a 180 degree phase splitter to generate a differential signal. The CRT requires large drive voltages, but almost no current. The oscilloscope bandwidth is limited by the amplifier chain as almost all electrostatic CRTs have a bandwidth extending to several hundred megahertz.
