Averaging Options

Auto Averaging—When you enable auto averaging, the sensor chooses an averaging number based on the power level currently being measured. For most power levels, selecting auto averaging results in the power reading fluctuating by no more than twice the selected auto average resolution setting. Auto averaging only stabilizes the readings caused by noise contributed by the power sensor electronics.

If you disable auto-averaging, you can choose from the following averaging methods:

• Moving averaging is continuously performed over a specified number of measurements, which is known as the averaging count. When a specified number of measurements is completed, the average is calculated. As the next measurement is taken, the average is recalculated from the new start and end positions. Moving averaging creates a more smooth reading. The following figure shows moving averaging performed over eight measurements.
  
  
• Repeat averaging is performed over the specified averaging count. The displayed power is updated after the next batch of measurements is complete. The following figure shows repeat averaging performed over eight measurements.
  
  
  Note   The USB-5680 supports only repeat averaging.
