  • TEM Antenna

    Techimp HQ S.r.L

    TEM antenna is a partial discharge sensor designed to receive electromagnetic (EM) emissions from a PD occurring in the monitored asset (like MV switchgears or LV and MV induction motors fed by power electronic impulses). It is a broadband antenna with a flat response which makes TEM suitable in a number of different applications. It has been optimized to operate in a frequency range typical for PD activity and it was designed to provide maximum sensitivity and high gain. Its compact and robust design (passive sensor) makes TEM the optimal sensor for direct installation on medium voltage Switchgears and motors. It can be virtually applied in any electrical equipment provided that it has apertures or EM transparent surfaces.

  • GSM RF Interference Test System

    Guangzhou Jumho Electric Co., Ltd.

    Cell phones and other wireless devices radiate powerful electromagnetic fields that can cause interference and noise in microphone signals. The interference and noise is called RF interference, which is an unwanted “signal” that occurs at the same time and frequency as a data signal. The RF interference disrupts the flow of data and degrades quality-of-service. Jumho Electric provides a cost-effective RF interference test system for GSM interference level measurement of wireless microphone.

  • Signal Conditioning

    Acces I/O Products, Inc.

    Sensors that are used to collect the data from the environment often don’t produce signal of characteristics optimal for an analog to digital converter (ADC) to translate to digital data. Additionally, these signals can be subject to electromagnetic interference (EMI) that introduces noise, having a negative impact on the reliability of the data. To make this analog input readable for the processing unit and dependable enough to give the desired quality of data the signal has to undergo a process of signal conditioning.

  • Surge Generators

    Hybrid - Hilo Test

    Surge pulses occur due to direct or indirect lightning strikes in a circuit or by switching transients caused by switching inductive loads or short circuits.

  • EM Explorer

    EM Explorer

    EM Explorer is a 3D electromagnetic (EM) solver for scattering problems of periodic structures illuminated by arbitrary incident fields including planewaves, Gaussian beams and focused Hi-NA beams. It can simulate both complex dielectric and complex magnetic materials including left-handed materials (LHM) that have a negative refractive index. EM Explorer is largely based on the same method of Finite Difference Time Domain (FDTD). Therefore it inherits most of FDTD's advantages and disadvantages. The advantages include simple & robust numerical algorithm, versatility for nearly any geometries, and good scalability of computing resources as a function of simulation volume size. The disadvantages are numerical dispersion and stability constraint due to the finite difference (FD) approximation to Maxwell's equations and explicit time marching algorithm.

  • RF over Fiber Link TX/RX

    L-Band - QuestTel

    QuestTel''s Satellite L-Band optical fiber Transmitter/Receiver set offers high pefromance and cost effective alternative to conventional coaxial systems. The L-Band Transmitter and Receiver pair is used for transporting L-Band RF over fiber from the antenna to the satellite receiver. Additionally transmitter provides optional 13/18V LNB power as well as Automatic Gain Control (AGC) to manage RF input level. By transporting the L-Band RF over fiber this range can be extended from several hundred feet to over 80 miles. Since optical signal is not affected by electromagnetic field, the quality of your signal will always stay at the high level. Also this fiber solution is more cost effective than coaxial system, as well as more reliable and flexible.

  • High Capacity Layout Pre-processor Element

    W2324EP - Keysight Technologies

    The High Capacity Layout Pre-processor Element is an ODB++ file format import and pre-processing tool that enables you select the environment immediately around critical nets in preparation for electromagnetic (EM) modeling. This type of pre-processing is useful in high-speed digital design where the printed circuit board (PCB) is very complex and whose total geometry exceeds the capacity of an EM-based field solver. The solution is to focus in on a handful of critical nets; for example, a differential pair connecting two Serializer/Deserializer (SERDES) integrated circuits (ICs) that is a victim of crosstalk from one or more aggressor traces. An example of such a trace is shown highlighted below in Figure 1. Note that the board has been "cookie cut" meaning a convex hull with a user-defined margin has been defined, leaving a portion of the board whose complexity is within the capacity constraints of full-accuracy, full-wave EM field solvers such as Momentum and FEM Element.

  • Near Field Probes 30 MHz up to 3 GHz

    RF2 set - Langer EMV-Technik GmbH

    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.
