Relative to RL

Chooses whether the limit line amplitude points are coupled to the instrument reference level, and
whether the amplitude points are expressed as an offset from the instrument reference level.

For example, assume you have a limit line, and the reference level at –10 dBm. If Relative to RL is
“Off”, entering a limit line segment with an amplitude coordinate of –20 dB displays the limit line
segment at –20 dBm, and the limit line segment will not change amplitude if the reference level
amplitude changes. If Relative to RL is “On”, entering a limit line segment with an amplitude
coordinate of –20 dB displays the limit line segment at RL – 20 dB, or –30 dBm. Furthermore, if
the reference level amplitude changes to –30 dBm, the limit line segment will be displayed at RL –
20 dB, or –50 dBm.

It is possible to change this setting after a limit line has been entered. When changing from On to
Off or vice-versa, the amplitude values in the limit line table change so that the limit line remains
in the same position for the current reference level settings of the analyzer.
