8 Frequency Scan Measurement
Meas Setup
For frequency limits and a frequency-domain X-axis, sets the Start and Stop Frequency to contain the
minimum and maximum Frequency of the selected Limit. The range between Start Frequency and Stop
Frequency is 12.5% above the range between the minimum and maximum Frequency so that the span
exceeds this range by one graticule division on either side.
For time limits and a time-domain X-axis, sets the sweep time to match the maximum Time of the selected
Limit.
If the domain of the selected limit does not match the domain of the X Axis, no action is taken. Standard
clipping rules apply, if the value in the table is outside the allowable range for the X axis.

Search Criteria
This menu lets you decide the Search mode.
When Peak Criteria Only is selected, performing a Search finds the peaks that met the Excursion and
Threshold under the Next Peak Criteria menu under the Peak Search key.
If Peak Criteria and Limits is selected, the search is also forced to consider the Limits and Margin if any of
them are turned on.
When Subranges and Limits is selected, the whole span from Start Frequency to Stop Frequency is divided
into equal width of subranges in log or linear based on frequency scale. The number of subranges depends
on the value of # of Subranges. Performing a search finds the peaks for each subrange, and the peaks that
exceed the Limits and Margin (if any of them are turn on) will be added into signal list.
