  • NEXTest 7

    PK-2030/2032/2033/2036/2037/2038 - Pansco, Ltd

    NEXTest 7 is an advanced and unique tester in the market.  It's designed to check and troubleshoot the pin connections of Display port & HDMI prior to installation on equipment. By using advanced technology to verify the integrity (20 pins + shield) of both display port and HDMI cables, especially for HDTV installation and DIY termination in the field, solving your cable testing need, unlink all of the other testers verify 9 circuits only. It checks for opens, shorts, miswires and intermittent faults in all conductors plus shield continuity, most tester only test for opens. It displays cable map results of both TX (near end) and RX (far end) on the main unit, either on testing before or after installation cables. User can easily read and determine the actual 21 pins configuration on main unit. It employs both auto and manual scanning of 21 wires. Tone Generator mode transmits two selectable tones on each pin for use with Net Probe (PR-06P) optional, enables one to quickly locate a cable. It's capable of testing up to 8 cables and locations at one time. NEXTest 7 especially features a self-learning mode to memorize cable pin out for testing large quantity standard or custom cables for PASS/FAIL a snap, makes testing quick and more efficient.

  • Emissions Test System

    PC-114 - Com-Power Corporation

    Perform Radiated & Conducted EMI pre-compliance testing at your facility up to 1 GHz. Com-Power PC-114 EMI emissions test system is a ideal solution performing pre-compliance EMC testing from 9 kHz - 1 GHz.. It has essential equipment needed for radiated and conducted EMI emissions measurements. The system includes a spectrum analyzer, antennas, near field probes, a preamplifier, LISN and a non conductive antenna tripod. Pre-compliance testing in EMC is a commonly used term not easy to define. In general, it implies testing done prior to formal testing for legal compliance. Formal legal compliance is performed at a facility designed and equipped with test instrumentation that is fully compliant with the applicable EMC standards. Such facility and instrumentation is capital intensive and can be expensive even to rent and not easily available. Compliance testing is performed per exacting requirements of the Standards and other reference documents adhering to the test methods and last detail. In addition, the test facility may require to be accredited by an accreditation body such as NVLAP, A2LA. Often it is desirable to know prior to compliance testing at such facility, whether a product is close to compliance and also how close. Pre-compliance testing is specially useful for specifications such as FCC, Part 15, EN 55022 or EN 55011 (CISPR 22 or CISPR11). Pre-compliance testing usually means using the full compliance methods but making a few educated compromises in use of site or equipment to reduce costs and testing time. Here are some benefits of pre-compliance testing.

  • Field Probe

    TNP6Gx - Triarchy Technologies Corp.

    A set of 4 near-field probe that is attached to any model of TSA mini spectrum analyzer that provide a easy mean of detecting and coupling unwanted signals to meet federal regulatory requirements.

  • Scanning Near Field Optical Microscope

    SNOM - A.P.E. Research

    SNOM microscopes employ SPMs precision of piezoelectric raster-scanning together with sharp probes to obtain light optical images at rather better than the usual wavelength-limited resolution. The possibility to go beyond the Abbe diffraction limit has been achieved with the Near-field light optical microscopes (SNOM or NSOM).

  • NeoScan

    EMAG Technologies Inc..

    NeoScan® is a unique electric field measurement system with unprecedented innovative features. NeoScan systems utilize EMAG’s patented, electro-optic (EO) field probe technology. Unlike conventional near-field scanning systems that require metallic pickup radiators or sensors, NeoScan probes are made of absolutely metal-free parts.

  • Single Probe Scanning Probe Microscope

    MultiView 2000 - Nanonics Imaging Ltd.

    an advanced single probe scanning probe microscope enabling a variety of modes of AFM/SPM/NSOM imaging. Nanonics has designed The MultiView 2000TM for excellence in scanning probe microscopy while allowing for near-field and far-field optical NSOM/Raman/TERS imaging without perturbation. The Multiview 2000TM is the only commercially available instrument that offers both tip and sample scanning. This versatility is important for different operation modes where the user can now choose whether the sample or tip is static. The Multiview 2000TM further offers the most stable feedback mechanism available in the form of normal force feedback with tuning fork actuation.

  • Near-Field Probes 100 kHz up to 50 MHz

    LF1 set - Langer EMV-Technik GmbH

    The LF1 near-field probe set consists of 4 shielded near-field probes used during the development process for emission measurement of longwave, medium wave, and shortwave frequencies on electronic devices. The probe heads of the LF1 set are designed for incremental detection of sources of electromagnetic interference on assemblies. First, the electromagnetic interference of the assembly is detected by the LF-R 400 probe from up to 10 cm. Then probes with higher resolution like the LF-B 3, LF-U 5 and LF-U 2.5 are used to more precisely detect any source of interference. The probe heads are designed for taking measurements at single pins and larger components. Near-field probes are small and handy. They have a current attenuating sheath and, therefore, are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The H-field probes do not have an internal terminating resistance of 50 Ω.
