Coax Test Solution
Test coax cable links quickly and easily with Coax Test Adapters
Extend the capabilities of your DTX CableAnalyzer to test coaxial cabling systems including legacy data cabling (such as 10BASE-2 or 10BASE-5 Ethernet) and video distribution coaxial cabling. Fluke Networks' new Coax Test Adapters and software upgrades add the following coaxial cabling tests to your DTX CableAnalyzer:
Cable Impedance
The cable input impedance characterizes the cable to be the proper type of coaxial cable such as 75 Ω cable versus a 50 Ω cable used in legacy Ethernet systems or 93 Ω cable. In addition, the tester performs a Time Domain Reflectometry (TDR) test of the link to ensure that the cable does not exhibit any significant changes in impedance. Such impedance anomalies can cause significant problems in the quality of the signal transmission.
Propagation Delay
Propagation delay measures the time required for signals to travel from one end of the cabling link to the other. The NVP of the cable, which indicates the speed of the electrical signals on the cable, is used to convert the propagation delay into the "electrical length" of the link. If the NVP is known with sufficient accuracy, the electrical length approximates the physical length closely.
Insertion Loss
With the DTX Coax Test Adapters, the DTX-1800 measures the insertion loss of the coaxial cable over the frequency range from 1 through 900 MHzx. The DTX-1200 measures insertion loss over the range from 1 - 350 MHz with the coax adapters. The tester stores the sweep diagrams that can be uploaded and stored on a PC using the LinkWare software.
