As an example, assume you have a frequency limit line. If the limit line
is specified as fixed, entering a limit line segment with a frequency
coordinate of 300 MHz displays the limit line segment at 300 MHz. If
the same limit line table is specified as relative, it is displayed relative
to the analyzer center frequency and reference level. If the center
frequency is at 1.0 GHz, a relative limit line segment with a frequency
coordinate of 300 MHz will display the limit line segment at 1.3 GHz. If
the amplitude component of the relative limit line segment is –10 dB,
then −10 dB is added to the reference level value to obtain the
amplitude of the given segment (reference level offset included).
A limit line entered as fixed may be changed to relative, and one
entered as relative may be changed to fixed. When changing between
fixed and relative limit lines, the frequency and amplitude values in the
limit line table change so that the limit line remains in the same
position for the current frequency and amplitude settings of the
analyzer. If a time and amplitude limit line is used, the amplitude
values change but the time values remain the same.
