Chapter 1 - Introduction
The Digital Solution
OMNIScanner is the most advanced hand-held certification and diagnostic
tool for Category 7, 6, 5E (Enhanced), 5 and ISO Class F, E, D, and C
links. With an extended frequency range of 300 MHz, OMNIScanner
provides full software compliance with TIA and ISO/IEC requirements for
measurement reporting and analysis (including Length, Delay, ACR, NEXT,
ELFEXT, Return Loss. Resistance, PSNEXT, PSACR, PSELFEXT and
Attenuation).
The Graphical User Interface and Accompanying
Software
OMNIScanners graphical user interface consists of a backlit LCD display,
quick access menus, arrow keys, and descriptive menu options that guide
you through certifying or troubleshooting cabling systems. PC-based
software expands the user interface and aids with the management of
projects.
OMNIRemote
For test and certification of twisted pair cabling, the OMNIScanner requires
the OMNIRemote unit at the opposite end of the cabling link under test.
OMNIScanner communicates with OMNIRemote to obtain status and
perform measurements from both ends of the link. OMNIRemote is
equipped with a speaker to generate tones, and several colored LEDs to
indicate overall test results and status.
OMNIScanners Display
Scanner Display Function
1-2 or 12/36: The paired numbers in the display indicate wire
pairs. For example, 1-2 indicates the wire pair of
pins 1 and 2. 12/36 indicates two wire pairs tested,
the first pair of pins 1 and 2, and the second pair of
pins 3 and 6.
