The Tektronix 7000-series oscilloscopes experienced switching electrical power supplies. They have been impressive in which they were being on the list of early samples of resonant materials. The improvements within the Tek supplies arrived from Gene Andrews, a Tek engineer in 7000 series who was their designer.
