  • Near Field Probes 1GHz - 10 GHz

    SX set - Langer EMV-Technik GmbH

    The SX1 set consists of 3 passive near field probes for making measurements in the development phase of E-field and magnetic field with a high clock frequency in the range from 1 GHz to 10 GHz. The probe heads of the set SX allow for measurements close to electronic assemblies, e.g. on single IC pins, conducting paths, components and their connectors, to localize interference sources. Field orientation and field distribution on an electronic assembly can be detected through trained use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They have an internal terminating resistance.

  • UV Accelerated Weathering Testers

    Dongguan Amade Instruments Technology Co., Ltd

    UV accelerated weather tester is also well known as UV test chamber, which is a type of environmental test chamber using fluorescent UV as light source to determine the resistance of plastics, leathers, rubbers, fabrics and so on to weathering under the specified conditions. We know that Ultraviolet light only accounts for 7% of the total sunlight, but it plays a core role in deterioration of materials. Not only does the ultraviolet, but UV test machine also can simulate dewing, high temperature, high humidity, black environment to be reappeared as a circulation. So UV weathering test is an essential measure for people to research and know the degradation state of specimens in advance as the time goes on.
