TRANSISTOR DRIVEN BEAM SWITCHING TUBE DECADE COUNTER

摘要

This paper describes an electrical readout, decade counter employ¬ing the magnetron beam switching tube with transistor drive. Double pulse resolution is one microsecond. The unit will accept a variety of transistor ' types and will tolerate supply voltage variations of ±20% at ambient temper¬atures up to 60°C.nA "Pixie" neon indicator is driven without the use of additional transistors. A readout circuit for printer on punched paper tape is presented.
