Late summer: Jack Murdock, Miles Tippery, Howard Vollum (and later Glenn McDowell) decided to
incorporate a company to produce their first oscilloscope. Because WW2 was over and the government had suddenly no need for electronic parts, the guys were able to buy "tons" of wanted parts for only a fraction of
January 16, 1946: Each of the four founders had to buy 26 shares at $100 to give the company the capital. Jack Murdock´s friend and lawyer Jim Castles did all the inital "paper work" and
organisation and got one share for that.

The 511 was more than a repacked 501. It was more sensitive, more compact and had a wide-band
circuitry. The 511 used a delay line to permit watching the "trailing edge" and a distributed amplifier to obtain high bandwidth. The screen had a precise grid (graticule) to perfrom a accurate
measurement and had a triggered sweep to view artefacts. Last but not least the entire instrument used regulated power suppies. The 511 oscilloscope was a great success and it was a "cash cow" for Tek .

The demand of the 511 increased rapidly. One “key” was the first (!) ad of tektronix in
Elektronics magazine in Arpril 1948. The ad showed the 511 but Tek simply called their one-and-only product “Vollumscope”.
Introduction of the 511A oscilloscope: It was the first application of a high frequency power supply. This technique achived advantages in space, weight and efficiency (=less heat) of the entire scope.
Introduction of the 512 oscilloscope: Low-frequency input signal could force the trigger and unblank the beam..
Tek introduced the modular 160-Series. It contained the 160 Power Supply, 161 Pulse Generator,
162 Wave-Form Generator. The basic design was provided by Ropiequet.
