The SignalTEK NT has additional test functions such as fiber optic and active network test capabilities. It can test network load by simulating different traffic over the switch with both copper and fiber interfaces. It also has Ping, Traceroute, PoE, Hub blink test capability

“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 credibility and b) are often only done single sided. The testers give an 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 the IEEE 802.3 standard. By running 100Mbit/s or 1000Mbit/s Ethernet at 100% load on the link from both sides provides users with 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 packet error rate by simply counting the transmitted and lost packets. Depending on which SignalTEK tester, these tests can be done on the structured cabling, but also on a live Ethernet network.

SignalTEK NT has optical and RJ45 interfaces to support testing over cabling and active networks

Yes. By downloading the software upgrade from www.trend-networks.com

The “Edimax EW-7811Un” USB Wi-Fi adapter is the only approved and compatible adapter for the TREND AnyWARE app. This adapter is included with the SignalTEK NT (R156003) and the SignalTEK CT kits (R156004). If you purchase the USB Wi-Fi adapter from TREND US please quote part number “WIFI-ADPT”.

No: the indications of optical power, voltage, length etc. are for troubleshooting only and do not need calibration. Transmission testing also doesn’t require calibration.

No: The optical power is indication only for troubleshooting. It is not a calibrated measurement even with a calibrated source, accurate attenuation measurement is not possible

Use of other SFPs may be possible but is not guaranteed for correct operation, including optical power indication

Yes. Active remotes No.2~ No.12 (part no. 150050) can be used for advanced wiremapping. However VDV II’s Active Remote can not be used with SignalTEK NT

Repetitive use wears the gold plating on all RJ45 contacts and this is accelerated when testing with PoE because of the electrical arcing. The replaceable connector contacts eliminate the need to return the tester to a service department for routine connector replacement.

The SignalTEK NT is a hand held transmission tester with key network troubleshooting functions that software tools such as command prompt or laptops can not provide. Can not provide a transmission test to confirm the cable or link available bandwidth They pose a risk to the network because their operating systems can be vulnerable to infections from viruses or malware. Slower detection of link and IP information such as duplex, speed, port ID, VLAN, DHCP, Gateway status and IP address Can not detect services such as ISDN, POTS, PoE or perform wiremap tests Do not have fiber interfaces or field replaceable RJ45 connectors Many cable environments involve small areas, above ceilings, behind walls, in floors etc. Fitting a laptop into these small areas could damage the laptop and makes the job difficult to complete.

The SignalTEK NT near and far end unit first try to build up an Ethernet connection on a cable to demonstrate if an Ethernet link is possible. If the SignalTEK NT near end unit can’t connect to the far end unit via an Ethernet link, both testers fall back into cable mode” where only wiremap and wire tracing is possible Note: Establishing an Ethernet link does not guarantee full Ethernet performance. Only the cable performance test will test if full Ethernet throughput at 1000Mb/s or 100Mb/s is possible. Some competitive testers will qualify a link with no more than a successful Ethernet link establish check.

Yes
