Apply Offset to Limit Table
Adds the X and Y offsets to each point in the limit table, then resets the X and Y offset values to zero. This
has no effect on the position of the limit trace.
For example, if the X offset is –10 MHz and the Y offset is 1 dB, the values in the limit table will be updated
as follows: 10 MHz will be subtracted from each X value, 1 dB will be added to each Y value. The offset
values will then be reset to zero. The limit trace will not be moved and the limit table will be updated to
accurately reflect the currently displayed limit trace.

Scale X Axis

Matches the X Axis to the selected Limit, as close as possible.
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.
