Target: input the target value to be searched in the [Logarithm Value], and click [Execute] value. When marker moves to
the first target value at the right side of current marker position, continuously click [Execute] to make marker move to the next
target value at the right side until to the highest end of stimulus value, and then return to the lowest end of stimulus value to
search target value.
When selecting [Discrete Marker] in the [Marker Advanced Options], if a data point is respectively at both sides of
interpolative target value, marker will move to the discrete data point most close to the target value.
When clearing [Discrete Marker] in the [Marker Advanced Options], marker will move to the interpolative data point
equal to target value.
Left target: only searching the target value at the left side of current marker.
Right target: only searching the target value at the right side of current marker.
Bandwidth: when selecting bandwidth search function, set up level which drops from peak value at both sides in [level]
(defaulted as -3dB), click [Execute] to make bandwidth Measure at this level. Use marker 1~4 during Measure, marker 1
searches the maximum peak value, marker 2 searches the point at the left side of peak value dropping to the specified level,
marker 3 searches the point at the right side of peak value dropping to the specified level, and marker 4 searches the center
point of bandwidth, and the following data will be shown after the completion of Measure:
Marker1:
Bandwidth:
Center:
Q-value:
Loss:

[Execute]
Click [Execute] button to carry out marker search with specified type once.
c)
[Tracking]
When selecting [Tracing] check box, Analyzer shall implement search function after the completion of Sweep each time according to
the current search type and settings of search domain, thus it can be ensured that marker is at the expected position after Sweep
every time. If marker Tracing function is on, the stimulus value of search marker can be manually set up.
6.1.4. Marker Function
Status settings of Analyzer can be changed by Stimulus marker position, such as initial frequency and stop frequency.
