Relative Limit Lines
Relative limit lines are X/Y coordinates that are referenced to the center frequency (X-axis) and
acquisition (Y-axis).
Use relative limits to test devices or signals that are identical except for the center frequency or
amplitude. With relative limit lines in place, you change the center frequency of the measurement
and the limits look as though they are in the same location.
The same is true for acquisition. When you expect to measure a different power level, instead of
changing the Y-axis value of all of the fixed limits, simply change to relative limits. The limits will
then remain a constant Y-axis distance from the acquisition.
Each limit line can be changed at any time from Fixed to Relative, and Relative to Fixed.
How to Create a Relative Limit Line
The easiest way to create a Relative limit line is to create a Fixed Limit at a specific center frequency
“Relative Limit Lines” on page 462
. Then change the limit line to
Relative. The X/Y data points will be re-calculated relative to the center frequency and acquisition.
Build From Trace
A limit line can be built from an existing trace. One X/Y point is made from each measured data
point. Then, using an offset value, you can shift the limit line UP for upper limits or DOWN for lower
limits.
