Abstract

The controller ensures discrete control of the signal level with a step of 1 dB and dynamic control range of up to 50 dB. The specified attenuation is stable to within ±1% in a temperature range of 10–30°C. Increased stability is achieved by using two functionally separated electrically controlled attenuators called unit and decade attenuator, respectively. The controller operation modes include an electric manual control and an automatic control from an external microprocessor with either a visual inspection of the controller state through a digital indicator or an automatic testing of this state using an external microprocessor.
