Createc
CREATEC Gesellschaft für Elektrotechnik GmbH was a German company founded by Manfred Koslar in Berlin in 1981.
Their only product line was a series of battery-powered, hand-held digital oscilloscopes. These scopes were re-branded by Gossen/Norma and Hitachi. Tektronix rebranded their entry modell as the T201, but also offered this modell with a different user interface as the T202.
