Power Line Meter
The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

Power Line EMI Adapters
How much EMI noise is on your power lines indeed? How to assess the levels of noise and its properties when it is obviously a bad idea to connect your oscilloscope or a spectrum analyzer directly to your power lines?Our EMI interface adapters provide a barrier for high mains voltages but a straight passage for high-frequency signals so that you can connect your sensitive instrument to power lines for analysis and quantification. We offer plug-in and hand-held adapters which can measure both differential ("normal") and common-mode noise.

Magnetic Resonance Instruments
Integrated Dynamics Engineering
MRI systems represent a significant investment. As magnetic resonance images can be distorted by electromagnetic fields, frequently the location is isolated by passive shielding to somewhat insulate the detectors from image distorting EMI. But for a fraction of the cost of the machine an active EMI compensation can fully protect the image from damaging fields generated by other electrical equipment, passing traffic, elevators or other nearby equipment.

Emissions Test System
PC-114
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.

RF Architectural Shielding Products
EMI (Electromagnetic Interference) is often used interchangeably with RFI (Radio Frequency Interference). However, EMI can be any frequency of electromagnetic noise, whereas RFI is a relatively narrow range of electromagnetic noise on the EM spectrum. EMI Shielding can be used to mitigate electric and magnetic radiation across various spaces. Radio Frequency (RF) Shielding can be used to mitigate RFI with specifically designed enclosures that can block RFI. As well, RF Shielding can include application of RF Shielding paints, fabrics, and other materials.

Near Field Probes 30 MHz up to 3 GHz
RF2 set
The RF2 near field probe set consists of 4 passive near field probes for measurements in the development phase of the magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF2 set allow the step by step localization of interference sources of the RF magnetic field on assemblies. From greater distances the electromagnetic interference can be detected by RF-R 400-1 and RF-R 50-1 probes. The RF-B 3-2 and RF-U 5-2 probes with their higher resolution can more precisely detect the interference sources. Field orientation and field distribution on an electronic assembly can be detected through a trained special 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 do not have an internal terminating resistance.

EMF Measurements/EM Measurements/Electromagnetic Radiation
Holland Shielding Systems B.V.
Electromagnetic fields cause interference in electronic devices and may affect the health of people close to where the fields are generated. It is important to recognize this at an early stage in a construction process, for instance at a future construction location or while construction is already underway, so that budgets are not exceeded. By means of field-strength measurements one can chart the existing electromagnetic fields and radiation emitted by GSM, UMTS antennas and transformer spaces, to mention a few examples. These measurements can help determine the best location in the new building for rooms where sensitive measurements are to take place, e.g. in hospitals or nano laboratories. And last but not least, field-strength measurements can detect sources of interference and can be part of a scheduled check of existing screened spaces and Faraday cages.
