Test splitters
The Coax Clarifier™ and dB Loss meter can profile the quality of a network
containing splitters.
Note:
Using F-Terminator Plugs on unterminated splitter outputs
(or cable ends connected to the splitter) will improve network
quality and lower dB loss.
1.
Connect the Coax Clarifier™ to the head of the network.
2. Run separate tests for each cable in the network.
a. Connect the dB Loss meter to the remote ends of the
cables to measure the dB loss/gain at each remote
point of the network.
to perform the test. These accessories will not be included in the loss
measurement reading.
3. When the dB Loss meter is calibrated to the network being tested,
disconnect the meter from the Coax Clarifier™.
Measure network Insertion loss
1.
Connect the Coax Clarifier™ to one end of the network and the dB
Loss meter to the other end of the network. The dB Loss meter will
show a loss/gain value, measured in dB, for the network at the
selected frequency.
Note:
The measured insertion loss excludes any adapters or
extension cables present during calibration.
2. Measure the network insertion loss at the selected frequency (10.0
MHz, 20.0 MHz, 30.0 MHz, or 40.0 MHz).
Note:
Look for large insertion loss variations between frequencies
at a single port. Any variation greater than 4 dB indicates a
problem that requires investigation and resolution.
