Insertion Loss
Insertion loss is the loss of signal strength over the cabling.
Insertion loss is caused by the resistance of the copper wire
and connecting hardware and by leakage of electrical
energy through the cable’s insulation.
At higher frequencies, signals tend to travel only near the
surface of a conductor. This “skin effect”, along with the
cabling’s inductance and capacitance, cause insertion loss to
increase with frequency.
Running Single Tests
The tester’s single test mode (SINGLE TEST on the rotary
switch) lets you run individual tests for isolating cabling
failures and quickly testing repairs. You can run some single
tests without a remote. Table 5-2 shows which tests require
a smart remote.
Single tests use the selected test limit to produce a PASS/
FAIL result for the test.
To save a single test, press
N, select or create a cable ID;
then press
N again.
