2 Operating Your Frequency Counter
82 Keysight 53150A/151A/152A Operating Guide
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.
