Note 1. 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.
