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:
http://na.support.keysight.com/fieldfox/help/SupHelp/FieldFox.htm
The actual sweep time is shown on the FieldFox screen. See the Screen Tour
on “Screen Tour” on page 2-12. 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.
How to set Sweep Time
—Press Sweep 3
.
—Then Min Swp Time
.
— Enter a value using the numeric keypad.
— Press a multiplier key. Learn about multiplier abbreviations in “Multiplier
Abbreviations” on page 2-14.
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.
How to set Output Power
—Press Meas Setup 4.
—Then Output Power
.
Measurement speed specifications do NOT apply in Temperature Control
Mode. Learn more in
“Temperature Control Mode” on page 2-5.
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.
