Impulse Noise - DTX CableAnalyzer
|The test takes noise voltage samples every second on pair 3,6. The user can change the threshold from 10 mV to 500 mV. |
To extend battery life, connect the ac adapter when monitoring impulse noise for extended periods. The testers power down timer is disabled during the impulse noise test.
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 dial to MONITOR and turn on the smart remote; then connect to the testers to the ends of the cabling.
3. Press .
4. To adjust the noise threshold, press to Stop; then use the and keys to change the value. Press to resume testing.
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.
To stop the test at any time, press .
If you disconnect the tester and smart remote during the impulse noise test, it takes several minutes for the remote to stop testing.
