oscilloscope
The KSDK7730/RT is one of the parts of the SCHUTZINGER oscilloscope, which is a popular German-made, analog oscilloscope. The KSDK7730/RT, also known as the Oscilloscope Focusing Tube, is a vacuum tube containing a hot cathode, designed to amplify electrical signals. It consists of a glass tube with a metal base, containing two control grids and two plates that interact with the electron beam emitted from the cathode. The control grids are used to either focus or spread the beam, controlling the resolution of the oscilloscope curves. The plates are used to control the amplitude or size of the current through the tube. The KSDK7730/RT also helps prevent interference from external electromagnetic fields, which is important for producing accurate results when using the oscilloscope for measurements.
