10 Gigabit Ethernet Analyzer 45
7 Asymmetric Test
Asymmetric test function is used to check operability of communication
link that has different data transmitting and receiving parameters
(throughput etc) — asymmetric channels.
Note: The option is not included in the basic configuration; should be purchased
additionally.
Measurements of the asymmetric channels parameters should be
performed independently for each direction. Therefore, the test traffic
transmission is produced in one selected by the user direction.
By testing two ETS-1000G should be used: local and remote. On the local
device the test parameters are set. The remote device is on the other end
of asymmetric channel.
Testing results are displayed on the screen of the local device.
Note: Tests for which the function is available are BERT and RFC 2544:
throughput, frame loss, back-to-back. RFC 2544 latency test is not available.
