  • 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.

  • Trifield Meter

    100XE - Alpha Lab, Inc.

    The Trifield Meter is a gaussmeter, electric field meter, radio field strength meter in a single unit. When measuring electromagnetic fields (EMFs), the primary concern is usually magnetic fields, which can be tricky to measure. If a less sophisticated 1-axis gaussmeter is used, a reading of zero could result even where the field is strong. A 1-axis meter must be oriented correctly to measure the field (which is a vector). The 3-axis Trifield Meter solves that problem by measuring the true strength of the field regardless of which way it is oriented. Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Another section of the meter detects AC electric fields, which can exist independently of AC magnetic field. The third section detects radio/microwave, such as from a leaky microwave oven.

  • 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.

  • Radar Level Gauge

    HRRD730 Series - HighReach Measuring & Controlling System Co.,Ltd

    At The Radar Level gauge Antenna emits and Narrows at The Microwave Pulse. This Pulse propagates in Space AT at The Speed of Light. The When IT Encounters at The Surface of at The the Measured Medium, Part of the ITS Energy IS the REFLECTED the Back and Received by at The Same, Antenna. At The Time interval The Between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium.Because the electromagnetic wave propagation speed is extremely high, the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). It is difficult to confirm. The 90X series 26G radar level gauge uses a special demodulation technology To accurately identify the transmitted pulse and the time interval of the pulse is received to further calculate the distance of the antenna from the surface of the measured medium.

  • Capacitive Proximity Sensors

    SICK Sensor Intelligence

    Sometimes you need to know what is hidden beneath a surface. Behind a wall, for example, inside a storage container, inside a shipping container, or behind a cover. Capacitive proximity sensors are ideal for level and feed monitoring. From solid material, such as paper or wood, to granules or liquids, they can be relied upon to detect what is happening in the production process and during final inspection. Is there something behind that cover? Is the finished package really full? How much paint is still left in the tank? For capacitive proximity sensors, these are easy questions to answer. SICKs capacitive proximity sensors are never far from the action. Sensing ranges between 1 and 25 mm allow them to be used in nearly all installation situations, making them extremely adaptable for a wide range of applications. These sensors are also remarkably resistant to interference. Impurities, contamination, dust, and airborne spray particles have little effect on them, nor does electromagnetic interference. No wonder they are installed in a wide range of industries, such as food and automotive, or in storage and conveyor systems.
