How to set Sweep Time
—Press Sweep 3.
—Then Min Swp Time
.
— Enter a value using the numeric keypad.
— Press a multiplier key. Learn more 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 Power
.
—Then Output Power
.
— High (Default setting) Sets output power to the maximum achievable
power at all displayed frequencies. Please see “Specifications/Data
Sheet” on page B-3 for expected power levels.
— Low Sets output power to approximately –27 dBm,
— Man Set output power to an arbitrary value,
—Then press Nominal Power
.
— Then enter a value using the numeric keypad, the arrows, or the
rotary knob.
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.
