1.1
Verifying Composite Clock Waveforms
NOTE
References to common, but differing, parameters between the Total Access
3000 and the Total Access 3010, such as number of slots, will be conveyed
by the convention a/b. The “a” represents the Total Access 3000 parameter
and the “b” represents the Total Access 3010 parameter. For example, the
differing number of access slots in the two platforms, 28 for the Total Access
3000 and 22 for the Total Access 3010, would be displayed “28/22.”
1.1.1
Introduction
This procedure details the test steps which must be performed to verify that the
composite clock inputs and outputs on the Total Access 3000/3010 shelf meet
requirements to ensure proper clock recovery throughout the clock chain.
1.1.2
Prerequisite Procedures
Before beginning this procedure, you should have completed the installation tasks
detailed in DLP-702.
1.1.3
Tools and Materials Required
• Oscilloscope with dual trace capability
•
Two scope probes
WARNING
To prevent electrical shock, do not install equipment in a wet location or
during a lightning storm.
CAUTION
Electronic modules can be damaged by static electrical discharge. Before
handling modules, wear an antistatic discharge wrist strap to prevent damage
to electronic components. Place modules in antistatic packing material when
transporting or storing. When working on modules, always place them on an
approved antistatic mat that is electrically grounded.
