Figure 30 Setting the Measurement Resolution
Set the Graph Display Type
When the Site Analyzer collects data during a sweep, it can be set to measure 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 data points
because of its physical pixel limitations. However, if the trace contains 475 data
points or 949 data points, all points are represented on the display. There are
three modes available to display the data points for the trace - envelope, maxi-
mum, 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 (mini-
mum) magnitude data point for each pixel.
Note: When saving (or downloading) a trace, all measured data points
(238, 475, or 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.
