right side of the target point is greater than that on the left side, while
the negative target conversion type means that the measured value on
the right side of the target point is less than that on the left side. Click
the
Transition
command in the
Target
submenu to select the
conversion type to search for. The
Both
option means that both
positive and negative target conversion types are regarded as valid
targets.
After the target value, transition
type and search domain are
determined, the target search can be started. The vector network
analyzer has the following target search modes:
⚫
Use the
Target Search
command in the
Target
submenu to search for the nearest
effective target from the current marker position to the right. When no effective target
can be found from the right, search from the starting point of the search domain to
the right.
⚫
Use the
Targe
t Right → Search
command in the target submenu to search the
nearest valid target from the current marker position to the right.
⚫
Use the
Target Left ← Search

Target
submenu to search the
nearest valid target from the current marker position to the left.
5. Multi-peak search:
Press the
Search
button on the front panel to search for multiple peaks in the
Multi
Peak & Target
submenu. Before searching for multiple peaks, you need to set the threshold,
deviation, and peak polarity in the
Peak Threshold
,
Peak Excursion
and
Peak Polarity
commands in the submenu to define the peak validity. After setting the above parameters,
click the
Multi Peak Search
command to search all effective peaks from the starting point of
the search domain to the right, and mark the peaks with a marker. Since there can only be 9
common markers on a single trace, only the first 9 effective peaks can be found when there
are many effective peaks.
6. Multi-target search:
Press the
Search
button on the front panel to search for multiple targets in the
Multi
Peak & Target
submenu. Before multi-target search, you need to set the target value and
conversion type in the
Target Value
and
Transition
submenu to define the target validity.
After setting the above parameters, click the
Multi-Target Search
command to search all
valid targets from the starting point of the search domain to the right, and mark the searched
targets with a marker. Since there can only be 9 common markers on a single trace, only the
first 9 valid targets can be found when there are many valid targets.
7. Tracking search:
When using the above search function, the marker position is only based on the current
sweeping result, and will not be dynamically updated with the trace update after the search.
Tracking mode can be used to update search results with trace data. Press the
