CREATEC Gesellschaft für Elektrotechnik GmbH was a German company founded by Manfred Koslar in Berlin in 1981.

Manfred Koslar
Createc SC01

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).

Key Specifications

Bandwidth 6/9 MHz
Resolution 7 bit (V)
Memory between 9 and 46 waveforms, depending on the model
Sampling rate 10 or 20MS/s, depending on mode and model
Single-shot performance 2MHz
External interface serial + parallel
Dimensions 257mm x 111mm x 48mm
Display resolution 128 x 128 pixel
Features
  • Signal processing (add, subtract, multiply, divide)
  • Cursor measurements
  • Zoom function
  • Waveform parameter measurements
  • partial automatic calibration
  • Multimeter mode
  • Display maximum error of current measurements
  • Independent timebases for each channel
  • Auto scaling for X and Y available
Options
  • Real time clock
  • parallel + serial interface
  • built-in drivers for various printers
  • improved "super twisted" LCD
  • dual analog path with 2 A/D converters
  • increased memory depth
  • DOS software (Createc Wave)
  • External battery pack + transport cases

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.
