Margin
Selects a margin for this limit, which will cause a trace to Fail Margin when the trace is between the limit
line and the margin line. Portions of the traces that pass the limit but fail the margin will be displayed in an
amber color. .
A margin is always specified in dB relative to a limit. Since there is only an upper limit in the Frequency Scan
measurement, the margin is always negative. If a value is entered with the incorrect sign, the system will
automatically take the negative of the entered value.
When the Margin is selected, it may be turned off by pressing the Margin key until Off is underlined. This
may also be done by performing a preset. Margin is the default active function whenever the margin is on,
and it is not the active function whenever the margin is off.
The margin lines are displayed in the same color, but paler, as limit lines. If the limited trace is blanked
then the limit line and the margin line will be blanked as well.
