Increase Dynamic Range - Keysight N9923A FieldFox User Manual

 Settings that are NOT listed above are NOT affected by the recalled display states.
 Changes to the above settings outside the Big Readout menu will be overwritten

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.
With an S21 trace active:
1. With RF OUT (port-2) open, press Trace 6 then
2. Re-connect the DUT.
3. Press
NA (Network Analyzer) Mode
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.
