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
— Lower the IFBW: Press BW 2 then
— Increase Averaging: Press BW 2 then
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.

overwritten when Big Readout (A or B) is selected. For example, suppose
the display format for the B state is Log. If you change the display format to
Lin using the standard menu (Meas 1, Format), the setting will show on the
display. But if you then use the Big Readout (A | B | OFF) setting, when B is
recalled, the Lin setting will be overwritten with the original Log setting.
