All SignalTEK testers are transmission testers. We have been referring to them as qualifiers in the past, but a review of functionalities of our products and those of our competitors have shown that our SignalTEK series is superior to the testers that our competitors call qualifiers.

“Qualifier” or “qualification testers” try to determine if Ethernet might work on cabling by running an un-calibrated measurement of physical parameters like signal-to-noise-ratio and delay. The problem with those tests is that they a) have no traceable accuracy to international standards and therefore have only a very limited reliability and b) are often only done single sided. The testers give a more or less reliable indication that Ethernet might work, but are not able to prove that. Additionally these testers are only able to perform this limited test on the structured cabling itself, but not through an Ethernet network.

“Transmission testers” transmit Ethernet packages according to IEEE 802.3 on a link. By running 100Mbit/s or 1000Mbit/s Ethernet at 100% load on that link from both sides of the link, these testers give users a clear reading if the link really can support the desired Ethernet speed. IEEE802.3 specifies a maximum bit error rate for every Ethernet speed. By running Ethernet packets bidirectional over a link, transmission testers are able to clearly determine if the link performs to the maximum bit error rate by simply counting the transmitted and lost bits or packets. Depending on the transmission tester, these tests can be done on the structured cabling, but also on a live Ethernet network.
