Limit Menu
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.
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, allowing 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.
