N8122W is an industrial cable fault analyzer from Fluke Networks. With the help of this instrument, users can perform cable tests for coaxial, twisted pair, or optical cables. It can be used for troubleshooting and diagnosing cable faults in data or voice networks in various industries, such as telecommunications, aerospace, automotive, and oil and gas. This article will discuss the industrial application fields of the N8122W, and its working principle.

N8122W can be applied to various data and voice network systems. In data networks, it can be used to determine the cable structure, calculate the network topology, or detect the cabling of non-functional trunk lines. In voice networks, it can be used to troubleshoot telephone lines, wireless systems, or even a public address system. The instrument is also capable of testing AM/FM/TV cable networks, and identifying applications with special features like cable cross interference, RF leakage and signal integrity. aside from these, the N8122W also has an optional device for inspecting the insulation integrity of the cables.

The working principle of N8122W lies in its ability to measure both signal strength and impedance. The instrument can be set to run a variety of tests, including DC resistance, Return Loss, Time Domain Reflectometry (TDR) and Frequency Domain Reflectometry (FDR). In these tests, the instrument is able to analyze the characteristics of various components in a cable segment, such as capacitance, inductance, and noise. After analyzing all these parameters, the instrument can generate a report which includes the cable performance, faults, and the length of the cable section.

In addition to the tests mentioned above, the N8122W is also able to measure the power sum equal-level far-end cross-talk (PSELFEXT) of the cable. PSELFEXT is a measure of signal interference between signals on different pairs of a multi-pair cable. This is an important part of a networking system, as it determines the quality of the data transmission in a network. In addition, the instrument can also be used to detect ground faults and open circuits, in order to identify all possible faults in the cable.

All in all, the N8122W is an industrial cable fault analyzer which is ideal for a wide range of networking systems. With its ability to measure signal strength and impedance, this instrument can be used to troubleshoot and diagnose cable faults in data or voice networks in various industries. It is also able to measure the power sum equal-level far-end cross-talk of the cables, detect ground faults and open circuits, and generate a report which includes the cable performance, faults, and the length of the cable section.
