Increase Dynamic Range
Dynamic range is the difference between maximum input power to the 
FieldFox receiver (without compressing the receiver), and the minimum 
measurable power (noise floor). Measurement accuracy is increased when the 
DUT response is at least 10 dB above the noise floor. For a measurement to be 
valid, input signals must be within these boundaries. 
The following settings will increase the dynamic range of your NA mode 
measurement. 
—Increase Power Level: Press Meas 4
 then Output Power High
— Lower the IFBW: Press BW 2 then IF BW
— Increase Averaging: Press BW 2 then Average
The following procedure MAY increase the dynamic range of your NA mode 
measurement. The results you see will depend on the performance of your 
DUT. 
With an S21 trace active:
1. With RF OUT (port-2) open, press Trace 6
 then Math and Memory then 
Data->Mem
2. Re-connect the DUT.
3. Press Data Math
 then Data-Mem
