The '''Tektronix 105''' is a 25 Hz to 1 MHz square wave generator. It was designed by [[Howard Vollum]] and Charles Sanford. It is all tube. | |||
The 105 has a d'Arsonval meter on its front panel indicating the current frequency. | The 105 has a d'Arsonval meter on its front panel indicating the current frequency. | ||
The frequency meter works on the principle of moving a constant amount of charge per cycle, integrating this charge into a current, and measuring the current. | The frequency meter works on the principle of moving a constant amount of charge per cycle, integrating this charge into a current, and measuring the current. | ||
The output is generated at the plates of three [[6AG7]] triodes that run in parallel. | |||
