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. Learn more at the FieldFox Supplemental Online Help:

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.
Power Level settings in this mode will NOT change Power Level settings in
other modes. To help prevent damage to your DUT, use caution when
changing modes with your DUT connected to the FieldFox test ports.
