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 the entry modell as the T201, but also offered this modell with a different user interface as the T202.

Block diagram
Service documents aren't available. But Mr. Koslar luckily filed nearly 200 patents (including all country variants) during his life. At least five of them are related to the SC series. These patents not only include a block-level based function description of the complete deivce - also the functionality of the proprientry ICs are described.
- United States Patent 4433303A: Push-pull amplifier circuit with FETs
- United States Patent 4746771A: Slde switch
- United States Patent 4839638A: Programmable circuit for controlling a LCD
- United States Patent 4897599A: Signal processing device with a level adapter circuit
- United States Patent 4906916A: Signal processing device having high speed shift register
