3.2 Swept SA Measurement
Auto Excursion
Toggles whether "Peak Excursion" on page 327 is determined automatically or
manually.
The default is ON, which means that Peak Excursion is automatically calculated.
Manually setting the Peak Excursion value sets Auto Peak Excursion to OFF.

Example Turn Pk Threshold Line on:

The Peak Threshold line is green and has the value of the peak threshold (for
example, “–20.3 dBm”) written above its right side, above the line itselft. If "Peak
Excursion" on page 327 is ON, it shows on the left side as a region above the Pk
Threshold Line. As with all such lines (Display Line, Trigger Level line, etc.) it is
drawn on top of all traces.
The Peak Threshold and Peak Excursion lines can be adjusted using the step keys,
knob, or numeric keypad. They can also be dragged on the display with your finger
or a mouse.
