1 BEFORE STARTING OPERATION
This section provides guidelines for turning-up the Digivance system, verifying that all units are
operating properly, testing to ensure that all performance requirements are satisfied, and
correcting any installation problems. This process assumes that the various units have been
installed in accordance with the system design plan.
1.1 Tools and Materials
The following tools and materials are required in order to complete the procedures in this
section:
• Portable spectrum analyzer or RF power meter
• AC/DC voltmeter
• External attenuators (if specified in system design plan)
• PC-type computer with Digivance Element Management System (EMS) Version 3.01
software installed
• Straight-through RS-232 DB-9 interface cable (accessory)
• Handset
• Pencil or pen
• Writing pad
