When the Resolution is changed after a calibration is performed, the cal becomes
interpolated. Learn more on page 51.
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.

User‟s Guide:
The actual sweep time is shown on the FieldFox screen. See the Screen Tour on
page 17. 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.

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 18.
Output Power
Set the power level out of the FieldFox to either High power or Low power.
Generally, the high power level (default setting) is more accurate because the
receivers are measuring farther from the noise floor. However, some devices are
sensitive to high power levels. Use the Low power setting when measuring
amplifiers.
NOTE
To help prevent damage to your DUT, when Output Power is changed in CAT
Mode, it is changed to the same value in NA Mode.
How to set Output Power
