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 require more time to complete an entire
measurement sweep.
When the Resolution is changed after a calibration is performed, the cal becomes
interpolated. Learn more on page 77.
How to set Resolution
 Press Sweep 3 .
 Then Resolution.
 Then choose one of the following:
 Using SCPI, Resolution can be set to any number of points between 3 and
Sweep Time
The fastest possible sweep time is always used as the default setting. Use the Min
Swp Time setting to slow the sweep time when measuring long lengths of cable.

The actual sweep time is shown on the FieldFox screen. See the Screen Tour on
page 18. To increase the sweep time, enter a value that is higher than the actual
sweep time. The increase will not be exactly the amount that you enter, as the
actual sweep time is the composite of many factors.
NOTE Measurement speed specifications do NOT apply in Temperature Control Mode.
Learn more on page 13.
How to set Sweep Time
 Press Sweep 3.
 Then
 Enter a value using the numeric keypad.
 Press a multiplier key. Learn about multiplier abbreviations on page 19.
Output Power
Set the power level out of the FieldFox to High, Low, or manually set power level
to a value between High and Low.
Generally, the high power setting is used when measuring passive, high-loss
devices to place the signal farther from the noise floor. However, for devices that
are sensitive to high power levels such as amplifiers, use the Low power setting.
For best measurement accuracy, use the Manual power setting at -15 dBm. After
calibration, the power level can be decreased for amplifiers, or increased for
higher dynamic range.
