The test takes noise voltage samples every second on pair
3, 6. The test produces a PASS/FAIL result if the selected
standard specifies a noise limit.
Monitoring impulse noise without a smart remote
may produce unreliable test results.
To monitor impulse noise:
1 Attach twisted pair link interface adapters to the tester
and smart remote.
2 Turn the rotary switch to MONITOR and turn on the
smart remote; then connect to the testers to the ends
of the cabling.

Tip: Fluke Networks recommends a noise threshold of
30 mV with an average pulse rate below 0.01/sec for
testing 1000BASE-T (Gigabit Ethernet) cabling.

If you disconnect the tester and smart remote
during the impulse noise test, it takes several
minutes for the remote to stop testing.
Figure 3-23 describes the impulse noise test results.
