Using Instrument Functions
Using limit Testing
Sometimes you may only be interested in the level at one particular
frequency. In this case, you may wish to use a single point limit. Using the
setup from the previous examples and building on them, let’s that
when testing your it is specified that the insertion loss at
174 MHz must be less than 3 The following example creates a single point
limit at -3 at 174 MHz.

Limit tests are only performed on actual data points, the interpolated
values between. When setting a single point limit, the limit is actually
applied to the closest data point to the frequency of the set limit. See
“Additional Notes on Limit Testing,” later in this chapter for more
information.
