FIELD: physics.
SUBSTANCE: for each signal value at the control input of the desensitisation device the signal detection threshold is determined, for which attenuation of the attenuator is gradually reduced from the maximum value until the target appears on the display screen. The level of its attenuation is fixed as well as the damping value inserted by the desensitisation device. The difference in damping values of the attenuator, fixed during transmission of logic-1 level and logic-0 level signals to its control input is determined. The desensitisation device is considered to be correctly functioning when the obtained value of the insertion attenuation exceeds its permissible value.
EFFECT: better quality of control due to determination of values of insertion attenuation.
