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):
GHz
MHz
