IF Bandwidth

Reducing the IF receiver bandwidth reduces the effect of random noise on a
measurement. However, narrower IF bandwidths cause longer measurement
times.
For highest accuracy, Zero AFTER changing the IF Bandwidth. Learn about
Zeroing in

How to set IF BW

— Press BW 2
— Then
— Then choose from the following:

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.
