However, in using special techniques, such as multi-channel oscillography employing the voltage-coincidence method—to be described later—higher writing speeds are encountered and tubes are of great help. Magnetic shielding of electrostatic tubes—Electrostatic tubes generally need to be shielded from the effects of stray magnetic fields from devices.
