3-15 Limit Menu
Limit lines can be used for visual reference only, or for pass/fail criteria
using the limit alarm and Pass/Fail Message keys. Limit alarm failures
are reported whenever a signal crosses the limit line.
Key Sequence: Limit (6) or Limit
Limit
Active Limit (Upper Lower): This key toggles the
active limit line settings to the Upper or Lower limit.
Limit State (Off Single Segmented): This key sets the
limit line state to Off, Single, or Segmented. See
Figure 3-51, “Limit Line State Menu” on page 3-63. Limit
line amplitude is stored even when turned off.
Note: Both the Upper and Lower limit lines for a trace
must be of the same type: either both are Single, or both
are Segmented.
Move Active Limit: Press this key to change the
amplitude of the limit line with the Up/Down Arrow keys,
rotary knob, or the numeric keypad. If the limit line is
divided into segments, then all segments move by the
same amount.
Edit Segments: Press this key to display the Segments
menu and a table of limit line segments. Tap a segment
(Upper or Lower), and then choose a function from
Figure 3-52, “Limit Line Segments Menu” on page 3-63.
Limit Alarm (On Off): When turned On, the Limit Alarm
sounds a repeating beep when the trace touches the limit
line.
Pass/Fail Msg (On Off): When turned On, a Pass or
Fail message is displayed to indicate whether the trace
touches or exceeds the limit line (Fail).
Limit Preset: Turns the limit line off and clears
amplitude information. The next time that a limit line is
turned on, it will be displayed at the default location
(center of the display).
