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
