  • AC/DC Power Meters


    Ethernet switches, routers and gateways have their distinct purposes and it is important to test their performance well. During R&D and DVT products are usually tested on L2/L7 while in production basic L2/L3 tests are usually sufficient. For those who follow testing methodology RFC 2544 and RFC 2889 are also available. IP traffic packet generators/analyzers for 10/100/1000 Mbps, gigabit and 10 gigabit with PoE options are the most important test instruments to ensure Ethernet switch or router product quality is verified. Gigabit TAP analyzers, media convertors, production test software suites and Ethernet cable emulators are additional tools used in conjunction with stream generators to help ensure fast development cycle and high quality. Our IP performance test systems are economic and known worldwide for excellence in quality and service support.

  • Power of Ethernet PoE Testing


    A test chassis with power load modules that act as PD (powered device) of PoE (power over Ethernet). It can support up to 16 modules (for power that is less then 20 Watt) per chassis and they are able to be cascaded as a chain with more test modules for more DUT.

  • Reclosers


    Automatic Circuit Reclosers (ACRs) are a class of switchgear which is designed for use on overhead electricity distribution networks to detect and interrupt momentary faults. Also known as Reclosers or Auto-reclosers, ACRs are essentially medium voltage rated circuit breakers with integrated current and voltage sensors and a protection relay, optimized for use as an overhead network distribution protection asset. Commercial ACR's are governed by the ANSI/IEEE C37.60, IEC 62271-111 and IEC 62271-200 standards. In ANSI countries three major classes of operating voltage are 15.5 kV, 27 kV and 38 kV.

  • Rail Vacuum Circuit Breakers


    Rail Vacuum Circuit Breakers are usually multi-functional AC vacuum circuit breakers combined with several other functions such as Disconnect Switches, Earthing Switches or Pantograph Interlocking valve making them a unique and small unit. Small size and light weight make vacuum circuit breakers perfect solution for rolling stock running on 15 kV or/and 25 kV railway networks. In addition to operating frequency of 50 Hz and 60 Hz sometimes 16.7 Hz frequency is also required. Because of rail vacuum circuit breaker location on the train and wide operating temperatures on the train routes temperature from -50 C to + 70 C is also one of the requirements.

  • Network Switch Tester

    NuStreams P9M - Omnicor

    NuStreams-P9M is a standalone tester for testing residential gateway (IP sharing devices) with 8 LAN and 1 WAN at wirespeed. The compact and lightweight design and built-in tests make it an ideal solution for production test on production line and for analysis and troubleshooting at service centers or maintenance outlets as well.

  • Network Testing and Simulation Tools


    Network IP traffic packet generators are used for network performance testing under maximum or partial throughput conditions. Network health can be analyzed by network traffic measurement in a testbed network, using an IP network traffic generator such as IP Traffic Test and Measure. The traffic generator sends packets, often with a unique packet identifier, making it possible to keep track of the packet delivery in the network. Network impairment simulation (emulation) is a technique for testing the performance of real applications over a virtual network. The aim is to assess performance, predict the impact of change, analyze impairment conditions or otherwise optimize technology decision-making. Measurements usually focus on simulation of conditions like delay, jitter, latency, dropped packets and limited bandwidth.

  • Network Active TAP

    NuTAP-302 - Omnicor

    NuTAP-302 is portable network TAP equipment that can monitor and redirect any data streams that flow through this equipment. Network TAP is a method for monitoring dynamic situation of network without intruding it.

  • Network Active TAP

    NuTAP - Omnicor

    NuTAP provides a safe, secure and cost-effective way for the deployment of IDS sensor into full-duplex links by aggregating both directions of the full-duplex streams on up to 4 different network segments into a single 1000Mbps monitoring port. The IDS sensors could then see both conversations on each side of the monitored network segments with only one interface. Because the IDS sensor is hidden behind the TAP, it’s shielded from direct attacks from the link being monitored.

  • Network Active TAP

    NuTAP-303 - Omnicor

    NuTAP-303 is portable network TAP equipment that can monitor and redirect any data streams that flow through this equipment. Network TAP is a method for monitoring dynamic situation of network without intruding it.

  • Network Gateway Testers

  • Surge Arresters


    Surge arresters are devices for protection of electrical equipment from over-voltage transients caused by atmospheric or internal switching events. Sometimes called a surge protection devices. They are designed to divert excessive voltages to ground and thus protect equipment in power transmission and distribution systems.Many types of surge arrestors are available in both polymer and ceramic housing and for AC and DC applications. Typically designed to cover voltages from 6.6 kV to 1000 kV arresters protect distribution transformers, power equipment, cables and power station equipment. In special environments metal oxide varistors, also known as zinc oxide (ZnO) blocks, can be used inside GIS housing, pole mounted distribution transformers and power transformers. Prevailing standards governing this type of technology are IEC 60099-4 and IEEE C62.11.

  • Fixed Vacuum Capacitors for RF Matching Networks


    Fixed vacuum capacitor Low power applications

  • Hand Held Test Systems


    In general, to perform a loopback test requires two test ports on both packet generator and DUT/NUT for transmission and receiving of test packets. It may not be available to do the loopback test in real network environment if the network under test is located far away from the packet generator with only one linked network cable.
