Single or Continuous Measure
This setting determines whether the FieldFox sweeps continuously or only once 
each time the Single
 button is pressed. Use Single to conserve battery power 
or to allow you to save or analyze a specific measurement trace.
This setting can be changed at any time without affecting calibration accuracy.
How to set Single or Continuous
—Press Sweep 3.
— Then choose one of the following:
— Single
   Automatically sets Continuous OFF and causes FieldFox to 
make ONE sweep, then hold for the next Single key press. Hold is 
annotated in the upper left corner of the display when NOT sweeping, 
and changes to an arrow --> while the sweep occurs.
— Continuous
 Makes continuous sweeps. This is the typical setting 
when battery power is not critical.
— You can also use Run / Hold +/-
 to toggle between Single and Continuous.
Resolution (Number of Data Points)
Data points are individual measurements that are made and plotted across the 
X-axis to form a trace. Select more data points to increase measurement 
resolution. However, more data points also takes more time to complete an 
entire measurement sweep.
When the Resolution is changed after a calibration is performed, the cal 
becomes interpolated. Learn more in “Interpolation *” on page 103.
How to set Resolution
—Press Sweep 3
.
—Then Resolution
. 
— Then choose from the following:  
101
 |201 | 401 | 601 | 801 | 1001 | 1601 | 4001 | 10001.
— Using SCPI, Resolution can be set to ANY number of points between 3 and 
10001. See the Programming Guide at
