3.2 Swept SA Measurement
Example
:CALC:MARK:AOFF
Couplings In the Swept SA measurement, sets the selected marker to 1
Couple Markers
When this function is ON, moving any marker causes an equal X Axis movement of
every other marker that is not Fixed or Off. By “equal X Axis movement”, we mean
that we preserve the difference between each marker’s X Axis value (in the
fundamental x-axis units of the trace that marker is on), and the X Axis value of the
marker being moved (in the same fundamental x-axis units).
Note that Fixed markers do not couple. They stay where they were while all the
other markers move. Of course, if a Fixed marker is being moved, all the non-fixed
markers do move with it.
This may result in markers going off screen.

3.2.7.3 Peak Search
The controls on this tab let you move the marker to selected peaks of the signal,
giving you enormous analysis capabilities, particularly when combined with the
Delta marker function.
In the Swept SA measurement, for a signal to be identified as a peak it must meet
certain criteria. Signals in the negative frequency range, and signals very close to 0
Hz, are ignored. If either the peak excursion or peak threshold functions are on, then
the signal must satisfy those criteria before being identified as a peak.
When "Peak Excursion" on page 327 and "Peak Threshold" on page 326 are both off:
–
Peak Search, Continuous Peak Search, and the maximum part of Pk-Pk Search,
search the trace for the point with the highest y-axis value that does not violate
the LO feedthrough rules. A rising and falling slope are not required for these
three peak search functions
–
The remaining search functions Next Peak, Next Pk Right, etc. only consider
trace points that have a rising and falling slope on the left and right respectively
