Effects of averaging on noise Averaging over 1 to 1024 readings is available for reducing noise. Table
1 provides the noise measurement for a
particular power sensor with the number of averages set to 16 for normal mode and 32 for x2 mode. Use the “Noise
Multiplier” for the appropriate mode (normal or x2) and number of averages to determine the total measurement noise
For example: For a Keysight 8481D power sensor in normal mode with the number of averages set to 4, the
measurement noise is equal to: (< 45 pW x 2.75) = <
124 pW
