Figure 14 Setting the Number of Measurement Data Points
Setting the Graph Display Type
When the Site Analyzer collects data during a sweep, the unit can specify that it mea-
sure 238 data points, 475 data points, or 949 data points. Selecting 475 data points
takes twice as much time to sweep as 238 points, and 949 points takes four times as
much time to sweep as 238 points.
The Site Analyzer display screen graph area can display only 238 points because of its
physical pixel limitations. However, if the trace contains 475 points or 949 points, all
points are represented on the display. There are three modes available to display the
data points for the trace: envelope, maximum, and minimum. For 238 data points,
there is no difference in the display for each of the three modes because each data
point occupies a separate pixel. For 475 data points and 949 data points, the envelope
mode displays all data points, the maximum mode displays only the highest (peak)
magnitude data point for each pixel, and the minimum mode displays only the lowest
(minimum) magnitude data point for each pixel.
Note: When saving (or downloading) a trace, all measured data points
(238, 475, 949) are saved (or downloaded). The display modes (enve-
lope, maximum, minimum) are for the Site Analyzer display only and are
not saved (or downloaded) with the trace.
