Using Limit Testing
Example 2
In this example, the analyzer has been set up with the following
parameters:
• Start frequency = 90 MHz
• Stop frequency = 210 MHz
• Number of points = 11
• Maximum limit line begin frequency = 90 MHz
• Maximum limit line end frequency = 200 MHz
Refer to the illustration below for the discussion. Around 199 MHz, the
data trace crosses through the limit line, and thus appears to have failed
the test. However, the analyzer shows the PASS indicator because the
last point tested is at 198 MHz. The last point displayed (210 MHz) does
not cause the limit test to fail because it is past the limit line end
frequency of 200 MHz.
