Using instrument Functions
Using limit Testing
To Use Relative Limits
There may be tunes when you are interested in the shape of a measurement
trace, but not concerned with the absolute amplitude. For example,
Figure 4-16 shows limit lines created for tuning a flter to a particular shape.
If the shape is more important than the amplitude, you can make the limit
lines relative to the peak point of the trace using the reference tracking
function.
In this example, you would press @EKE) Reference Tk&&zg
T;F~& PM&. The limit lines are now relative to the peak point on the
measurement trace rather than set at an absolute amplitude.
For more information on reference tracking, see “Using Reference Tracking,’
later in this chapter.
