NA (Network Analyzer) Mode
NA Mode Settings
Notes:
— To move a marker, press
Marker
, then
Marker
, then scroll to the marker
number to be moved. The new marker position can NOT be saved with the A
or B display state.
— 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 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.
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.
