2 Operating Your Frequency Counter
76 Keysight 53150A/151A/152A Operating Guide
Setting the Resolution and Measurement Rate
The number of measurements the Counter makes in a given amount of time is
affected by the Rate setting, the Resolution setting, and the quality of the input
signal (signal quality affects the amount of time the Counter requires to determine
an accurate measurement). By adjusting the Resolution and Rate settings, you
can affect how often the Counter takes measurements.
Setting the Resolution
The Counter’s resolution setting determines the number of digits displayed for
measurements and the precision of the measurements. Since less time is required
to compute each measurement as the resolution of the measurements is reduced,
the resolution setting also affects the rate at which measurements are taken and
displayed. As a result, the flash rate of the Gate indicator changes when you
change the resolution.
The numerals shown for the value of the measurement are displayed in four groups
of three digits, as shown below (the leading zero is suppressed):
