Article Number: 226533

Gigabit LAN Qualifier with Network Diagnostic Tool

Easy Cable Testing and Ethernet Speed Certification

The NetXpert 1400 provides a complete solution for cable qualification and troubleshooting of active networks, enabling rapid, simple verification and documentation of the capability of cabling links to support Gigabit Ethernet operation compliant with the IEEE 802.3ab standard.

Irrespective of the category of cables and connectors installed, a “Pass/Fail” result indicates whether the existing cabling can support data rates up to 1Gbit/s.

  • Tests network cabling and coaxial cabling
  • Qualifies data cabling for IEEE 802.3 compliance at transmission rates of up to 1Gbit/s (BERT)
  • Determines signal-to-noise ratio (SNR)
  • Measures delay skew
  • Performs full TDR for pair length and distance to fault measurements
  • Full-color wire map shows opens, shorts, miswires, and split pairs
  • Results can be saved in the tester, and standards-based measurement reports providing ”Pass/Fail“ results can be generated


  • Easy-to-use touchscreen helps you work faster
  • Increase your productivity with pdf test report generation directly on the tester
  • Extremely capable - on top of its qualification measurements, the NetXpert 1400 is able to perform active network tests

No fiber module is currently available.

Connect the NetXpert 1400 via the included micro-USB cable to your computer. Navigate on the device to "File Manager" and touch the three points in the lower selection box. Then select "USB" and confirm the dialog in order to operate the NetXpert as a SD card reader.

You have chosen an unshielded cable from the cable database. The cable, which you want to measure is shielded. The tester detects the error and stops the test. If your cable is unshielded and the SNR test stops, please contact us.

Since version 1.76 the NetXpert supports German, Spanish and English. Please undertake a firmware update to your tester. Download the firmware update package from our website.

I would like to check telephone cable with RJ11/12 connectors, but I cannot find a corresponding socket on the NetXpert 1400. Can I plug into the RJ45 socket?

Never push a RJ11/RJ12 connector into the RJ45 socket on the NetXpert 1400! The RJ45 socket can be damaged! Adapters of RJ45 to RJ11/12 are available fromretail sources. Use an adapter to check telephone lines with the NetXpert 1400.

Picofarad is a unit for the electrical capacity of a conductor. Picofarad per meter is the electrical capacity of a conductor over one meter. Knowing this, the length of a cable section can be calculated. The specific value of your cable type is listed on the datasheet. To determine the length of a cable , it is necessary to enter the correct value in the NetXpert 1400.

A "split pair" - error is a rare cabling error. It occurs when an identical mistake was made at the assembly on both sides of a cabling link. The white veins of two identical pairs are reversed at both ends, although consistent, the orientation of the wires causes very high crosstalk. The result: A communication of active components is not possible.

The "Dynamic Host Configuration Protocol" allows automation connection of computers without manual configuration to an existing network. IP address assignment and transfer of other parameters such as subnet mask, gateway or DNS-server name results in automatic configuration of the client. This can be tested using the NetXpert 1400 by acting as a DHCP "client" and requesting from the local "DHCP server" the relevant data.

"Power over Ethernet" (from the Engl .; "Power over Ethernet"), abbr .: PoE, is a technique where power can be supplied to network devices over the eight-wire Ethernet cable. The NetXpert 1400 performs a load test on voltage stability and detects any possible power classes and types.

The NetXpert 1400 supports IEEE 802.3af and (PoE +) and loads up to 25.5 watts (in class 4 detection of mode A or B).

The Link Layer Discovery Protocol is a manufacturer-independent protocol that provides the possibility to exchange information between neighboring devices on the network. In addition to the device name and IP address also the connected port, available speeds or VLAN ID, etc. can be read. CDP (Cisco Discovery Protocol) is the manufacturer specific protocol of the company Cisco with the same function. The NetXpert 1400 can retrieve both LLDP and CDP information from the neighboring device (switch, router, server, etc.).

The Internet Protocol Version 4 (IPv4) was the first version of the Internet Protocol, which was distributed and used worldwide. Each device on a network must be assigned a unique address so that communication between the devices can be take place. The 32 bit IPv4 address (e.g. is the most popular address type. IPv6 is the latest version of the protocol, which was introduced due to address shortage. NetXpert supports testing in networks with IPv4.

With a ping-signal the availability of devices on the network can be checked. If an ICMP "echo request"-package is sent to a participant in the network, a response must be returned, according to the protocol specification. If the participant received the packet, it sends an "echo reply" back. The availability and packet round trip time (Engl .: Round Trip Time) is displayed to the user. If the Ping target cannot be reached, there will be a feedback by the router or an error message (host unreachable).

Support for IPv6 networks is currently not implemented. This will be added in an upcoming firmware.

Yes, NetXpert 1400 can also ping URLs on the network.

"Signal to Noise Ratio" is a measure of the quality of a signal, It is defined as the ratio of the average power of the desired signal to the average noise power of the interference signal in dB. The NetXpert 1400 tests the signal-to-noise ratio on the various pairs and checks the conformity to the relevant limit for Ethernet standard. The cause of a SNR fault may be long cable lengths or low-grade components.

The skew is the time difference of signals on different pathways. Skew is measured in nanoseconds. If the twist in a twisted pair cable is irregular or the cable is too long, runtime differences of a signal between the individual cores (pairs) are generated and the receiver may not be able to evaluate the impulses as a single signal. Reasons for failure of Δ Lz. tests are components of inferior quality, long cable lengths or irregular cable twist.

The "Bit Error Rate Test" checks compliance to a certain Ethernet-speed. Through a period of 10 seconds, packets with full data rate (e.g. 10/100/1000 Mbit/s) are transmitted on the route. If no error bit appears, the test is passed.

Traceroute determines on which routers and Internet nodes IP-data packets are received at the requested computer. So the NetXpert 1400 displays all the stations that a ping-signal passes on the way to the goal. The IP addresses, as well as the run-time, are recorded and displayed in a table in chronological order.
