  • Double-Ridged Horn Antennas

    pdficon large Overview Double Ridged Waveguide Horn Antennas 

    The broadband horn antennas BBHA 9120 offer a very low SWR in their nominal frequency range and a very broad bandwidth. The gain increases with frequency up to approx. 21 dBi, depending on the horn's size and shape. The increasing gain with frequency helps to compensate cable losses. The BBHA 9120 series is suitable for both, transmission and receiving applications. The max. allowed Input Power is only limited by the coaxial connector. The detailed manual of the calibrated test antennas includes Gain, Antenna Factor, SWR and Directional Patterns. The antenna is mounted with the 22 mm tube, equipped with a Index Ring for quick changes of polarisation without using tools. We recommend the antenna mast AM 9144 together with the mast adapter AA 9202 as accessories.

  • Helmholtz Coils

    Helmholtz-Coils are especially designed to generate precisely defined magnetic fields from DC to the upper end of the audio frequency range and beyond. The generated fields are in a strongly linear relation to the coil current. The field- strength can be calculated exactly by analytical (or numerical) methods, based on the coils' geometry, the number of turns and the coil current.

    Therefore Helmholtz-Coils are ideally suited for the calibration of magnetic field probes or sensors. Typical applications are magnetic immunity testing according to automotive standards or MIL-461F.

    When generating magnetic fields with Helmholtz coils the coil current is directly proportional to the magnetic field strength.

  • Voltage Probe

    Voltage Probes

    In addition to EMI measurement with LISNs (Line Impedance Stabilisation Networks, Artificial Mains Networks), Probes are used for Terminal or Line voltage measurement.
    LISNs are required to feed the Equipment under Test (EuT) with mains power, to reduce external line interference, to offer the EuT a standardized impedance and to route the extracted r.-f. voltage to the EMI receiver.
     
    Probes are used for  terminal voltage measure ment, also on cables, output sockets, PCB traces. In many cases high input impedance and low capacitance is required for this purpose. Active Probes may not be used for general Interference measurement, as pulses could by far exceed the linear voltage range. This not only causes limiting and distortion effects but also intermodulation that changes the frequency distribution of spectral  components.
     
    These resistive dividing probes are perfectly linear and free of these effects.
     
    By the use of an AC and pulse-compatible input blocking capacitor (that is also free of partial discharge effects), EMI  measurement is also possible on AC power lines up to 250 V ac or DC sources up to 500 V.
     
    High-Voltage Probes up to 10 kV (20 kV) DC or 2 kV AC with 1500 Ω input || 4 pF input capacity are available as TK  9420.
     
    For the max. power line voltage of 250 V ac two probes are available with input resistances of 1.5 kΩ, and 2.5 kΩ with the model numbers TK 9420, and TK 9417.

    MagTest System

     

    The MagTest System is a system to generate magnetic fields and to perform tests regarding the susceptibility against magnetic fields in accordance with MIL-STD-461E (RS101), MIL461F, ISO 11452-8, EN 55103-1/2, EN 61000-4-8, SAE J1113-22, SAE J551-17 and other military or civil standards.

    Most automotive manufacturers have derived their own standards, among them:

    Peugeot Citroen B217110, Renault 36 - 00 - 808, Ford ES-XW7T- 1A278-AC and many others.

    A further application is the calibration of magnetic loop antennas or sensors.

    At least the system consists of a function generator as signal source, a power amplifier and a radiating loop or Helmholtz coil.

    The system components will be individually configured for your requirements.
