 X Axis: set the X-axis unit to frequency or time unit. Note that all the
points of the current limit line will be deleted when the X-axis unit
changes.
 Freq Interp: set the Freq Interp to Log or Lin. In Log mode, both the
frequency and amplitude use Log unit to make interpolation operation; in
Lin mode, the frequency uses a Lin unit and the amplitude uses a Log unit
for interpolation operation.
 Rel Setting: enable or disable Relative Frequency (Rel Freq) or Relative
Amplitude (Rel Ampt). When the Rel Freq is enabled, the frequency you
are editing is the difference between the frequency of the current point
and the center frequency. When the Rel Ampt is enabled, the amplitude
you are editing is the difference between the amplitude of the current
point and the reference level.
 Del Limit: delete the limit line you are editing.
 Fail Stop: select whether to perform the next sweep if the test fails.
 Beeper: turn on or off the beeper. When the beeper is on, it beeps when
the test fails.
