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.

Specifications

Markers 100 ns to 5 s, 1-2-5; pulse amplitude ~1 V; pulse width ~2% of period; accuracy ±0.01%
Amplitude Calibrator Square waves switched at 10kHz, 1kHz, 50Hz, 10Hz, 1Hz, also DC; amplitude 100 V to 0.025 V and 100 mV to 0.025 mV, 1-2-5; rise time ≤ 100 ns; 50 Hz output has rise time of 400 μs. Accuracy ±0.2% when loaded with 1 MΩ except 0.05 V/mV ±0.3% and 0.025 V/mV ±0.35%; output impedance varies from 5 kΩ at 50 V and 50 mV down to 75Ω at ≤ 0.5 V and 0.5 mV.
Fast Rise Signal Square waveform switched at 100 kHz, 1 MHz, 10 MHz; rise time ≤ 1 nsec; output 0.2 V max into 50 Ω
Television Waveform A 625 line signal, +ve and —ve modulation; amplitude 1.6 Vp-p; iutput impedance 75 Ω; -ve going output is DC coupled from earth, +ve going output is AC coupled.

Modulation is switch selected as:

Black
White
62.5kHz )
250kHz )
1MHz ) square waves.
5MHz )

Also modulation can be switched on and off at 1 sec rate.

Auxiliary Outputs Available on 4 mm sockets at the side; square waves at 10 MHz, 1 MHz, 100 kHz, 10 kHz, 1 kHz, 100 Hz, 10 Hz, 1 Hz; amplitude ~2.5 V, output impedance ~1 kΩ
Ext Clock External clock frequencies of 2V peak to peak amplitude may be fed to the 10 MHz Auxiliary Output socket.
Power Supply 100, 110, 120, 200, 220, 240 V, 48 to 440 Hz, 13 VA.
Size 107 mm × 228 mm × 285 mm (H×W×D)
