Stepped Edit Menu
Using the or within the edit list menu display the edit menu.
This menu lets you select measurement frequencies arbitrarily. Using this menu it is possible to
define the exact frequencies to be measured on a point-by-point basis. For example, the sweep
could include 100 points in a narrow passband, 100 points across a broad stop band, and 50
points across the third harmonic response. The total sweep is defined with a list of subsweeps.
The frequency subsweeps, or segments, can be
in any of the following terms:
n
start/stop/number of points
n
start/stop/step
n
center/span/number of points
n
center/span/step
n
CW frequency
The subsweeps can overlap, and do not have to be entered in any particular order. The
analyzer sorts the segments automatically and lists them on the display in order of increasing
start frequency, even if they are entered in center/span format. If duplicate frequencies
exist, the analyzer makes multiple measurements on identical points to maintain the specified
number of points for each subsweep. The data is shown on the display as a single trace that is
a composite of all data taken. The trace may appear uneven because of the distribution of the
data points, but the frequency scale is linear across the total range.
Once the list frequencies have been or modified, the list frequency sweep mode can be
