Overview
INTERCEPTOR 147 2 Mbit/s and Data Analyzer
Use LIST to present the results information as a
list of ASCII characters and skip to Step 6.
5. Set Printer Mode (GRAPH or ASCII).
For non-graphics printers, use ASCII (so that the
bars of the graph can be represented using ASCII
characters). For graphics printers, use GRAPH
or ASCII.
Specify the histogram print information.
6. Set the Hist Rslt item.
You can request a histogram for a single result or
histograms for all results.
7. Set Start and Len.
You can print all, or only a portion of, the
contents of the histogram buffer. Use Start to
specify the start time and Len to specify the
amount of time to be covered.
To print the entire contents of the histogram
buffer, set Start to 00/00:00 and set Len to AUTO.
If you find that all (or most) of the results are
clustered around a given time period, you can
create another Histogram Print — this time
“zooming in” on a smaller time period so that you
can see that time period in greater detail. (The
minimum span of time on which you can zoom in
is 60 seconds.)
Create the histogram.
8. Select the Hist Print? item and press SELECT.
5.6.1 Examples of Histogram Prints
The appearance of a Histogram Print depends on the
setting of Hist Type (GRAPH or LIST) and, if Hist Type
is set to GRAPH, the setting for Printer Mode (GRAPH or
ASCII).
