Data Performance Tests
One of the most important functions of SignalTEK NT is its ability to make data performance
tests of cables and active networks. These performance tests are designed to test the system
by sending Ethernet traffic through it, looping it back and checking it for errors. You can
choose whether to test according to the IEEE 802.3 standard for Gigabit Ethernet, which
requires that 10 seconds of full-rate traffic is transmitted through the system without errors, or
to set your own traffic rate and pass/fail limit.
Each of the performance tests operates on the principle illustrated in Fig 45:
1. Frames transmitted to Remote Unit at calculated Frame Rate for specified duration
2. Frames looped back by Remote Unit,
3. Received frames checked and counted.
