The Telequipment C3 is a solid state oscilloscope calibrator.
From the manual:
The Calibration Unit Type C3 is a small portable mains-operated instrument for use in service centres.
It provides a wide range of output signals, with a high degree of accuracy as shown in the Specification, for test and calibration purposes.
