Display Resolution

You can display either one digit or two digits after the decimal point for both
magnitude and phase readings.
This setting survives a Preset and Mode Preset.
How to set Resolution
 Press Scale/Amptd
 Then
 Then choose:

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, set IF BW before calibrating.
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 either High power or Low power.
Generally, the high power level (default setting) is more accurate because the
receivers are measuring farther from the noise floor. However, some devices are
sensitive to high power levels. Use the Low power setting when measuring
amplifiers.
NOTE To help prevent damage to your DUT, when Output Power is changed in CAT or
NA Mode, it is changed to the same value in VVM Mode.
How to set Output Power
 Press Meas Setup 4 then
 Then
VVM (Vector Voltmeter) Mode
setting of the arrows is based on the current span and can NOT be changed in
VVM Mode.
