The H20, H10, H5 and E5 are magnetic field (H) and electric field (E) probes for radiated emissions EMC pre-compliance measurements. The probes are used in the near field of sources of electromagnetic radiation. They serve to locate and identify potential sources of interference within the building blocks of electronic assemblies. The probes act similar as wide bandwidth antennas, picking up radiated emissions from components, PCB traces, housing openings or gaps and from any other parts that could be emitting RF. The probes are usually connected to a spectrum analyzer. Scanning the probe over the surface of a PCB assembly or housing quickly identifies locations which emit electromagnetic radiation. By changing to a probe with smaller size, the origination of the emissions can be further narrowed down. Additional applications are RF immunity tests by feeding a RF signal into the probe and radiating it into potentially susceptible circuit sections: Furthermore the probes can be used in the field of repair or debugging to track down issues in RF signal chains by contact less measurement of RF signal levels. One more application is non- invasive measurement of RF building blocks such as modulators or oscillators. Frequency, phase noise and spectral components can be measured in conjunction with a low noise preamplifier.

Every set includes a SMB to SMA cable (0.75m)

    Radiated emission tests are typically carried out in anechoic chambers, using antennas to pick up the radiated signals. Due to bandwidth limitations, several antennas are required to cover the complete frequency range. Furthermore, it requires much space and the cost of the equipment for a standard conformant setup is immense.
    An engineer of a small or medium size enterprise usually has to rely on his experience and on best practice methods in order to design an EMC compliant product. Nevertheless, it is estimated that > 50% of products fail testing first time around. Anytime an engineer sends a new product for compliance testing, it is a shot in the dark. Failing is very expensive. Not only that re-testing costs are high, but also the project schedule and market introduction gets delayed. 
    What is needed is an affordable laboratory set up to measure radiated emissions in the own lab, prior to compliance testing. A TEM cell is the right piece of equipment for desktop testing of radiated emissions. Tekbox developed open TEM cells to cover the complete frequency range up to 2GHz and with usability even at frequencies beyond. 
    Combined with a spectrum analyzer, products can be tested before and after EMC related design modifications.  A set up with a TEM cell will not deliver exactly the same quantitative results as a measurement in a certified test house, however it will give an excellent indication on whether the design suffers from excessive radiated noise or not.  The engineer will clearly see, whether his changes improved or deteriorated the EMC performance or whether it remained unchanged. Using TEM cells eliminates the guesswork.

    A TEM cell is a stripline device for radiated emissions and immunity testing of electronic devices. It is not a replacement, but due to its size and cost it is a convenient alternative to measurements in an anechoic chamber. 

    A TEM cell consists of a septum, the conductive strip in the centre section and walls which are connected to ground. The geometry is designed to present a 50Ω stripline. The device under test (DUT) is placed in between the bottom wall and the septum.

    The TBTC0/1/2/3 are so called “open TEM cells”, which got no side walls for convenient placement of the DUT. It may pick up RF background noise, which however can be taken into account by doing a measurement of the cell output signal before powering on the DUT. 

    Tekbox open TEM cells got a better frequency response compared to standard TEM cells of similar size. TEM cells suffer from higher order wave modes which limit the usable bandwidth. A unique design feature of the Tekbox TEM cells implements resistance perpendicular to the desired propagation direction of the wave. Consequently higher order wave modes and resonances are suppressed.
    All TEM cells are supplied together with a 50Ω/25W RF termination, a DC block to protect the spectrum analyzer or RF receiver input and a N-Male to N-Male coaxial cable.

    The TBLM1 LISN Mate is a companion device for LISNs, which splits the conducted noise signal into its common mode and differential mode components. The LISN Mate is connected to the output of a LISN inserted into the positive supply line and to a second LISN inserted into the negative supply line.

    The conducted noise signal at the output of a LISN is the sum of common mode and differential mode noise. The LISN mate splits it into the common mode and differential mode components, with each signal component available at a separate BNC port.

     

    SPECIFICATIONS
    • Frequency range: 30 kHz – 110 MHz
    • Maximum RF level at any BNC port: 27dBm
    • Maximum DC current at any BNC port: 30 mA

    Model Name/NumberTBOH01

    The TBOH01 5uH LISN is a device required to setup conducted noise measurements of DC-powered devices.

    It is designed to be used for EMC pre-testing in the frequency range of 150kHz to 110 MHz.
    The LISN is inserted into the supply line of the DUT (Device Under Test). Conducted noise which is present at the supply terminals of the DUT can be measured at the BNC connector using a spectrum analyzer or a measurement receiver.

    The source (supply) terminal and the DUT terminal are decoupled by a 5µH inductor.

    SPECIFICATIONS
    • Frequency range: 100kHz – 110MHz (1GHz, see figure 4 in the manual)
    • DC Resistance: 40 mΩ
    • Maximum current: 10A
    • Nominal operating voltage range: 0 – 60V DC *

    * The operating voltage range is limited to 60V DC for safety reasons. Though the component rating of the LISN is ≥ 200V, the positive supply voltage could accidentally be connected to the negative terminal of the LISN and thereby to the LISN housing. Under this circumstance, a DC voltage > 60V  could cause a lethal electric shock when touching the housing.
