The Tektronix 105 is a 25 Hz to 1 MHz square wave generator. It is all tube. 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.
It was designed by Howard Vollum and Charles Sanford.
