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.

Output Power

— High (Default setting) Sets output power to the maximum
achievable power at all displayed frequencies. Output power is NOT
FLAT across the displayed FieldFox frequency span. Please see
Appendix B:, "Specifications/Data Sheet," on page 831
expected power levels.
— Low Sets output power to approximately –45 dBm, FLAT across the
displayed FieldFox frequency span.
— Man Set output power to an arbitrary value, FLAT across the
displayed FieldFox frequency span. If flattened power can NOT be
achieved, a warning message and beep occurs. To achieve a
flattened output power, reduce the power level or stop frequency.
— Then press Power Level
— Then enter a value using the numeric keypad, the
