6-5 Limit Menus
To access the Limit Menu, press the Shift key, then the Limit (6) key.
Two types of limit lines can be specified, lower limit lines and upper limit lines. Limit lines
can be used for visual reference only, or for pass/fail criteria using the limit alarm. Limit
alarm failures are reported whenever a signal is above the upper limit line or below the lower
limit line. Limit lines cannot be used with Smith Chart or Polar graphs.
Each limit line can consist of a single segment, or as many as 40 segments across the entire
frequency span of the instrument. These limit segments are retained regardless of the current
frequency span of the instrument. Limit segments allow the configuring of specific limit
envelopes at various frequencies of interest without having to reconfigure them each time
that the frequency is changed. To clear the current limit setup configuration and return to a
single limit segment (starting at the current start frequency and ending at the current stop
frequency), press the Clear Limit soft key.
