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, handheld digital oscilloscopes which were released in 1986. These scopes were also re-branded by Gossen/Norma and Hitachi. Tektronix rebranded the basic model as the T201, but also offered the same model with a different user interface as the T202. The company probably closed in the early 1990ies (see link section).

Block diagram
Service documents aren't available. But Mr. Koslar luckily filed nearly 200 patents (including all country variants) during his life. At least six of them are related to the SC series. These patents not only include a block-level based functional description of the complete device - they also describe the functionality of the proprietary ICs.
