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. 참고: 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. 팁: 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  .  참고: If you disconnect the tester and smart remote during the impulse noise test, it takes several minutes for the remote to stop testing. |
