Chapter 2 Operating Your Frequency Counter

Setting the Number of Averages

In certain situations, the length of time that the AVERAGING message is displayed can be affected by additional factors. When you are measuring frequency, the current resolution setting, the rate setting, and the quality of the signal all affect the length of time required to make the measurements and complete the average computation.

If the measurement rate is set to HOLD, and a value larger than 1 is set for averages, the first set of measurements is not initiated until you press the Reset/Local key. When you do, the Counter displays the AVERAGING message while it takes the first set of measurements. When the first set of measurements is complete, and the averaging result is displayed, the Counter remains in this state until you press the Reset/Local key to initiate another set of measurements, change the value for averages back to one, or change the setting for the measurement rate to SLOW, MED, or HIGH. When the measurement rate is set to HOLD, the Counter performs a block-average computation instead of a running-average computation.
