SELECT
LIMIT LINE
The SELECT LIMIT LINE softkey activates the LIMIT LINES table and the
selection bar jumps to the uppermost name in the table.
The following information is offered in the columns of the table:
Name Enable the limit line.
Compatible Indicates if the limit line is compatible with the measurement
window of the given trace.
Limit Check Activate automatic violation check for upper/lower limits.
Trace Select the measurement curve to which the limit is assigned.
Margin Define margin.
Name and Compatible - Enabling limit lines
A maximum of 8 limit lines can be enabled at any one time. In split screen
mode, they may be assigned to screen A, screen B or to both screens. A
check mark at the left edge of a cell indicates that this limit line is enabled.
A limit line can only be enabled when it has a check mark in the Compatible
column, i.e. only when the horizontal display (time or frequency) and vertical
scales are identical to those of the display in the measurement window.
Lines with the unit dB are compatible to all dB(..) settings of the Y axis.
If the scale of the y axis or the domain (frequency or time axis) are changed,
all non-compatible limit lines are automatically switched off in order to avoid
misinterpretation. The limit lines must be enabled anew when the original
display is re-displayed.
