Keysight Technologies
Conducting all the parametric measurements necessary for the numerous test structures on a semiconductor wafer can be a time-consuming and expensive process. With the cost of end-user devices continuing to drop, even laboratory characterization environments must reduce the cost of test. Until now engineers and scientists working on current and future semiconductor process technologies were faced with a difficult choice: either use a semiconductor parameter analyzer with positioners on a wafer prober, which limits the ability to perform automated test, or use a switching matrix and probe card, which reduced the analyzer's measurement resolution. Utilizing a switching matrix with a semi-automatic or fully-automatic wafer prober enables characterization tests to be automated, eliminating the need to have an operator manually reposition the probes each time a new module needs to be tested. This reduces both test time and cost. Due to the many price/performance points available, Keysight's switching matrix solutions provide the flexibility to choose exactly what your testing needs require, without overspending.

mks Ophir
Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω

RMO-TW Series -
IBEKO Power AB
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test. Finally, a user can export all results in the form of a report.

ABB Ability -
ABB Ltd.
ABB Ability mobile gas leak detection system uses ABB’s patented Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS) technique which has a sensitivity and precision more than 3000 times greater than legacy methods. This enables identification of leaks several hundred feet away from the source. Current traditional leak detection technology is slow, laborious and costly. Operators walk on foot near the pipeline with hand-held sensors making paper-based reports.This is slow and can lead to dangerous leaks being missed or not identified in a timely manner. ABB’s Ability mobile gas leak detection system delivers a low cost per leak solution with low false positives. Reporting includes mapping of the leaks available via a mobile app and measurements as Cloud-based service. The system consists of ABB’s Methane/Ethane Analyzer, a GPS, a sonic anemometer and proprietary leak detection software that presents real-time geospatial maps of multiple gas concentrations in real time. The software’s sophisticated leak detection algorithm combines the system’s measurements of gas concentrations (CH4, C2H6), local coordinates (GPS) and local wind velocity (sonic anemometer) to estimate the location of the leak. Readings are stored in the device and can be transmitted in real-time to the cloud for centralized monitoring.

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.

IBEKO Power AB
Transformer turns ratio testers from TRT series are DV Power instruments mainly designed for the measurement of power transformer turns ratio. Also, they measure transformer excitation current and phase shift. Special tests, such as automatic vector group detection and magnetic balance, can be performed on three-phase transformers and three-phase autotransformers.All models, except TRT03 series, have a built-in true three-phase power source, which is necessary for testing turns ratio of transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.DV Power turns ratio testers can output various test voltages for different applications. From the extremely low test voltage of 1 V AC that enables turns ratio verification of the majority of current transformers, up to the highest test voltage of 500 V AC that provides the most accurate turns ratio testing of power transformers used in power generation and transmission. By using the external booster, test voltage increases up to 5 kV AC in order to successfully test capacitive voltage transformers.All DV Power turns ratio testers have a built-in tap changer control unit. Because of that, it is possible to control the on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, the instrument and included DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option significantly facilitates and shortens the turns ratio testing time.TRT turns ratio testers use the same set of cables as three-phase winding ohmmeter & tap changer analyzers from the TWA series. Consequently, it enables one-time cable setup for performing eight tests:turns ratioexcitation currentphase anglemagnetic balancevector group detectionwinding resistanceon-load tap changer DVtestand demagnetization.
