    E and H near-field measurements on electronic modules
    Near-field measurements are often performed, if a developer has to find out why an emission limit of an EMC standard is exceeded, for example. Based on field strength measurements, the developer already knows several critical frequencies of the device or module under test. A practicalway to reduce EMI is to analyze near fields, locate the sources and come up with targeted countermeasures.

    Special Probes ¸HZ-15
    Before you perform a near-field analysis,you first need to know how the E and H fields are distributed. The five probes from the Probe Set ¸HZ‑15 are well suited for this purpose. All near‑field probes are designed for ease of use, and are ideal for measuring high- frequency fields starting at 30 MHz on printed boards and on components. The magnetic field probes include special electrically shielded probe tips. The various probe tip shapes are designed for tasks in near-field measurements. The upper limit frequency of a probe is determined by the size and design of the probe tip. All probes are passive and are connected to the 50 W input of a test receiver or spectrum analyzer. The Preamplifier ¸HZ-16 increases sensitivity.

    Preamplifier ¸HZ-16
    Inserting the Preamplifier ¸HZ‑16 between the near-field probe and the spectrum analyzer makes it easier to measure very weak high-frequencyfields of up to 3 GHz. The input and output are provided as 50 W BNC connectors to allow you to use any spectrum analyzer.

    The E field probes
    The surfaces of bus structures, large components or supply structures emit E fields that can cause EMI. The bottom of the RS E 02 probe detects these fields on an area measuring approx. 2 cm × 5 cm.



    Characteristic in the 30 MHz to 1.5 GHz frequency range

    E field probe RS E 10

    The narrow electrode of the RS E 10 probecan select a single conductor track from a bundle of conductor tracks 0.2 mm in width. The light color of the probe tip stands out in sharp contrast to the dark green of the printed circuit board.


    Characteristic in the 30 MHz to 1.5 GHz frequency range

    The H field probes

    Owing to its large diameter (approx.25 mm), the RS H 4 00‑1 probe for H field is extremely sensitive and provides the average of the magnetic field strength in the loop area of the probe. You can use the probe at a 10 cm distance around modules and instruments.


    Characteristic in the 30 MHz to 1.5 GHz frequency range

    H field probe RS H 50-1

    The RS H 50-1 (diameterapprox. 10 mm) is higherin resolutionand lower in sensitivity than the RS H 4 00-1. It is suitablefor performing measurements at a smaller distance of up to approx. 3 cm. In this range, you can determine field distributionand field orientation even more precisely.


    Characteristic in the 30 MHz to 1.5 GHz frequency range

    The H field probes

    H field probe RS H 2.5-2

    The RS H 2 .5-2 H field probe can be used to selectively detect the current spectrum in conductor tracks and component leads such as on capacitorsor ICs. The probe tip has a magneticallyactive groove of approx. 0.5 mm in width.
