28、nd IEC 60050(161), as well as the following, apply. 3.1 common-mode point node in a circuit or at a PCB at which a single point is taken as signal terminal, the second terminal being the signals reference (forming a 2-terminal port). As an example of a common-mode point, the ground reference plane (
29、Vss-plane) at an edge of a PCB is considered with respect to an external reference, e.g. the bottom of the workbench Faraday cage. _ 1To be published. EN 62132-5:2006 6 3.2 common-mode port virtual node of a circuit or at a connector port at which the signal follows the vector sum of all signals (in
30、cluding ground) at that port in relation to a reference port. As an example, the bottom of the Workbench Faraday cage is considered an external reference. At a common-mode port with multiple wires, this node can be established by using a passive summation network. NOTE For a shielded (multi-wire) ca
31、ble, the screen of that cable is used as common-mode port terminal. In this case, the common-mode point is the screen of that cable. 4 General 4.1 Applicability This standard applies to ICs that can perform “stand-alone“ functions when used on a physically small test board. The RF immunity of these
32、ICs can be measured under pre-defined conditions. In addition, the method allows measurements on application boards. This gives the user an indication of the expected immunity once the IC(s) is implemented. This method makes it possible to classify ICs for dedicated functions where EMC constraints a
33、re applicable. This might apply to ICs used with cordless telephones, other communication devices and applications where EMC properties are important to obtain optimal operation e.g. automotive, process measurement and control equipment and all other products that control critical functions. 4.2 Mea
34、surement philosophy The workbench method is derived from the IEC 61000-4-6. The method described in that publication assumes that supply and signal cable(s) are attached to an electrically small test board, with dimensions /2, i.e. 0,15 m at 1 GHz, see note. These connected cables become the dominan
35、t antennas; the induced RF disturbance is injected to the test board via these “antennas”. NOTE The test board and its connected cables thereto should be partly supported by material with low dielectric constant, as such r= 1 is assumed, see also 7.7. The connected cables will have functions such as
36、 supply, communication and other signal interfaces and these cables are commonly not geometrically oriented in the same plane as the other cables. The antenna (common-mode) impedance per port has been normalised to 150 with tolerances in the various frequency bands. By injecting either a voltage in
37、series or a current through these common-mode impedances, the RF immunity test is established. Direct injection of RF disturbance to the IC package is very small, see also IEC 62132-2 as an additional measurement method, and often negligible compared to the disturbance injected through the connected
38、 cable(s). Due to the fact that induced currents will flow through the reference of the test board, indirect coupling between the voltages and currents through the package are also established. Because of the concept chosen, the workbench method shows the effect of the test board layout, the IC supp
39、ly decoupling, the RF performance of the used discrete components (capacitors, inductors) as well as the measures taken on the IC (e.g. on-chip decoupling, filtered inputs and Schmitt-triggers used, etc.). Similar modes of operation (by software or function) shall be used for the various ICs to be t
40、ested to allow comparison. In addition, various modes of operation with one IC allow comparison i.e. determination of contribution of individual blocks within the IC. EN 62132-5:2006 7 4.3 Basic test set-up The RF immunity measurements shall take place above a metallic reference plane, see Figure 1
41、for an open set-up (according to IEC 61000-4-6). With common-mode impedances defined by using the coupling and decoupling networks (CDNs), relations between the applied disturbance voltage, while testing against RF immunity, and the locally created E/H fields can be calculated. 4.4 Workbench concept
42、 In principle coupling and decoupling is similar to the method given in IEC 61000-4-6; see Figure 1. With this workbench method, a small Faraday cage is used. Discrete resistors, connected to several common-mode points (to the PCB ground) or ports (as referred to the signals) of the test board are i

The workbench basic set-up is shown in Subclause 7.3. 5 Test conditions The test conditions shall be as described in IEC 62132-1. The workbench method can be used for either absolute or comparative tes

When measurements are carried out using a test board other than defined in IEC 62132-1, that test board shall be described such that repetition of the measurement remains possible

EN 62132-5:2006 8 6 Test equipment The test equipment shall meet the requirements as described in IEC 62132-1. For the purpose of the RF immunity test, the open-circuit test generator voltage is defined. Ad

The test generator used shall meet the following requirements: RF generator capable of covering the whole frequency rang
