processor. Graphs show the test history for either the current test or a previously saved
test.
To use the graphs function:
1. Select a protocol processor that has been configured for Error Alarm testing.
2. From
Results , select Graph . The Graph screen appears. It contains two graphs
which allow you to display incoming alarms and errors.
3. Use the following buttons to control graphing parameters:
•
Sample Rate - Sets the timing for graph results at increments of 1
Second, 1 Minute, or 15 Minutes.
•
Change Scale - Compresses or expands the displayed time scale for the
graphed errors and alarms at time intervals of 30 minutes, 90 minutes, 3
hours, 6 hours, 12 hours, 24 hours, or 72 hours.

a later time.
Important: This is not a text file; when replayed, it appears as the
original graph plot. Choose Print a Graph to Report if you desire graph
information that can be printed out.)
•
Replay Graphs/Stop Replay - Replays or stops saved graph (.grp) files.
Shift Left and Shift Right
Use these buttons to adjust the graph's time scale to an earlier or later time.
•
Selecting Shift Left moves the graph's reference cursor to the left and displays
earlier events.
•
Selecting Shift Right move the graph's reference cursor to the right and displays
later events.
You may also adjust the graph's time scale by using your finger and dragging the
reference cursor to the desired time scale. As you drag the reference cursor, the Track

alarms that occurred during that time. An example of an SDH graphing results is shown
