For power supply at the time of test, use a constant-voltage power supply unless otherwise specified. Note 2. The output noise voltage is represented by the peak value on RMS scale (VTVM) of average value indicating type. For AC power supply, use an AC stabilized power supply (50Hz) to eliminate the effect of flicker noise in AC primary line.
