Four markers are turned on, and each has a dedicated use.
Marker 1 is a starting point from which the search is begun.
Marker 2 goes to the bandwidth center point. Marker 3 goes to
the bandwidth cutoff point on the left, and marker 4 to the
cutoff point on the right.
If a delta marker or marker is on, it is used as the
reference point from which the bandwidth amplitude is
measured. For example, if marker 1 is the delta marker and is
set at the
maximum, and the width value is set to
-3 the bandwidth search finds the bandwidth cutoff points
3 below the maximum and calculates the 3 bandwidth
and Q.
If marker 2 (the dedicated bandwidth center point marker) is
the delta reference marker, the search

If no delta reference marker is set, the bandwidth values are

(Option 010 only) is used to specify the parameters of the
window in the transform menu.
(Option 010 only) sets the pulse width to the widest value
allowed. This
the sidelobes and provides the greatest
dynamic range.
(Option 010 only) is used to set the window of a time domain
measurement to the minimum value. Provides essentially no
window.
(Option 010 only) is used to set the window of a time domain
measurement to the normal value.
the most useful
because it reduces the sidelobes of the measurement somewhat.
is used to terminate basic units: Hz, degrees,
or seconds. It may be used to terminate entries
such as averaging factor.
