o OFF causes a new marker search only when the search feature is re-
executed.
Moves the active marker to the HIGHEST amplitude data point of the
Peak
o
trace. Peak Excursion value is ignored. In SA Mode, the LO feed-through
signal (0 Hz) is also ignored.
(Not available in DTF) Moves the active marker to the LOWEST
Min
o
amplitude data point of the trace.
(NA Mode and Pulse Measurements ONLY) Enter the Target value.
Target
o
The marker moves to the first occurrence of the Target value to the right of
its current position. The FieldFox interpolates between measured data
points to find the exact Target value to two decimal points. The interpolated
X-axis value is displayed in the marker readout or marker table. Subsequent
presses of the Target softkey cause the marker to move to the right to find
the next occurrence of the Target value. When the marker reaches the end of
the stimulus range, it "wraps around" and continues the search from the
beginning of the stimulus range.
Bandwidth ON OFF
o
and OFF. When OFF, the marker table appears showing the X and Y-axis
positions of all enabled markers.
(NA Mode ONLY) Specify the level in dB from the peak or valley
Bandwidth
o
where bandwidth is measured.
o Negative numbers search for a Peak bandpass, such as a filter S21
response.
o Either of the following TWO methods can be used to search for a Valley or
Notch filter, such as the S11 response of a bandpass filter.
o Negative values search down from the TOP (MAX) of the response.
o Positive values search up from the BOTTOM (MIN) of the notch.
o If you first enter Negative, then Positive values, it may be necessary to
press Marker , then More, then
S21 of a filter with BW Markers and associated readout values.
The search criteria is -3 dB.
(NA Mode ONLY) Use to quickly toggle BW Markers ON
Markers All Off.
