Best answer
The correct choice is (c) 50 uV/cm

Best explanation: A typical value of the calibration signal is 50 uV/cm. A calibrating signal is used for controlling and documenting the sensitivity of the amplifier channels. This supplies a voltage step of adequate amplitude to the input of the channels.
