Pulse shape analysis
42 SmartClass E1 Tester User’s Guide
Pulse shape analysis
You can use the Pulse Shape feature to measure the height, width, rise time,
fall time, overshoot and undershoot, and signal level of an E1 pulse. The
results are displayed as text or as a graph of the pulse shape. You can also
measure the pulse for conformance to ITU G.703 specifications.
To perform pulse shape analysis
1 If you haven’t already done so, launch the E1 Pulse Shape test application
(see “Launching an E1 test application” on page 28).
2 From the E1 Pulse Shape menu, select Configuration.
The Configuration menu appears.
3 Connect the E1 Tester to the test access point, using the RX/TX1
connector.
4 To configure the test, do one of the following:
– If you want the E1 Tester tester to configure the interface, framing, and
pattern settings automatically, on the test menu, select Action, and
then select Auto Configure.
The unit will attempt to automatically configure the interface, framing,
and pattern. If the Auto Configure succeeds, proceed to step 7.
If this attempt fails, the E1 Tester will continue it’s attempt to configure
the framing settings, and the pattern will default to Live. You can also
configure the setting manually by selecting Configuration, and then
proceed with step 5.
– If you want to configure the interface, framing, and pattern settings
manually, on the test menu, select Configuration, and then proceed
with step 5.
5 Configure the interface settings. See “Specifying interface settings” on
page 30.
6 Configure the E1 framing settings. See “Specifying E1 framing settings” on
page 31.
7 Configure the E1 ABCD/Sa settings. See “Specifying E1 signaling (ABCD/
Sa) settings” on page 32.
8 From the E1 Pulse Shape menu, select Results and then select one of the
following:
– Summary displays a large “All Summary Results OK” message if no
anomalies or defects have been detected. If anomalies are detected,
results are displayed.
– Pulse Shape displays a graphical representation of the pulse.
NOTE:
Pulse Shape is an optional feature. It only appears if you have purchased
the pulse shape software option.
