26、 presence of conducted RF disturbances, e.g. resulting from radiated RF disturbances. This method guarantees a high degree of repeatability and correlation of immunity measurements. This standard establishes a common base for the evaluation of semiconductor devices used in equipment functioning in a
27、n environment subject to unwanted radio frequency electromagnetic waves. 2 Normative references The following referenced documents are indispensable for the application of this document.

Conducted disturbances 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 62132-1 apply. EN 62132-4:2006 6 4 General 4.1 Measurement basics The minimum
31、electromagnetic immunity level required for an IC depends on the maximum permitted level of RF disturbance to which an electronic system can be submitted. The value of the immunity level is dependent on system and application specific parameters. To determine the immunity performance of an IC, a sim
32、ple measurement procedure, and a measurement set-up in which resonances are avoided, is required to guarantee a high degree of repeatability. The following points out the base of this test. The largest geometry found in an integrated circuit is the leadframe. The size of the leadframe is in the rang
33、e of some centimetres or smaller. The dimensions of the structures on chip are even up to two magnitudes smaller than the dimension of the leadframe. For a frequency range below 1 GHz, this leadframe, as well as the structures on-chip, are not regarded as efficient antennas for the reception of unwa
34、nted RF energy. It is the cable harness and/or the traces of a printed circuit board which constitute efficient antennas. Thus, an IC receives the unwanted RF energy through the pins connected to the wires of such cables. Because of this, the electromagnetic immunity of an IC can be characterized by
35、 conducted RF disturbances (i.e. RF forward power) instead of field parameters as is usually the case in module and/or system testing. For module and system tests, the forward power provided to a circuit by the cable harness or the traces on a printed circuit board (PCB) acting as antennas can be me
36、asured or estimated. This power is considered to be a forward power delivered to the circuit, no matter whether it will be reflected or absorbed. In fact it has been observed that many ICs are most susceptible to the disturbances at quite high reflections. This is due to the fact that in this case e
37、ither injected RF currents or applied RF voltages reach the highest possible values. To characterize the immunity of an IC, the forward power needed to cause malfunction is measured. The malfunction may be classified from A to D according to the performance classes defined in IEC 62132-1. Figure 1 s

39、PreflIEC 2649/05 Key Pforforward power Prefl reflected power Figure 1 Arrangement of a direct injection test set-up The frequency variable RF generator provides the RF disturbance that is amplified by the connected RF amplifier. The directional coupler and the RF power meters are used to measure the
40、 actual forward power injected into the device under test (DUT). At the RF injection port the RF power is delivered to the test printed circuit board (PCB). The RF amplifier is decoupled by a DC block to avoid supplying DC into the amplifier output. The DC supply is prevented from getting RF power b
41、y a decoupling network that has a high RF impedance on the side that is connected to the RF injection path. To monitor the behaviour of the DUT an oscilloscope, or other monitoring device preferably with a pass/fail function etc., can be used. To decouple the RF signal crosstalk of the DUT from the
42、low frequency measurement performed by the oscilloscope, a second decoupling network is used. The measurement equipment can be optionally controlled by a computer, if desired. Any function inside an IC can be affected even if it is not connected to the pin under test. Therefore the operation mode(s)
43、 of the IC shall be chosen in a way that all functions of the IC are used during the test. ICs are often used in different configurations based on the application. In order to understand the influence of each individual pin, each pin that is expected to be exposed to RF disturbance should be tested
44、individually. Multiple pin testing is permissible into pins of differential mode systems. EN 62132-4:2006 8 The forward power needed to cause malfunction of an IC depends on several parameters, like those shown in Table 1.

46、ircuitry connected to a pin Knowledge of the immunity of an IC (the highest forward power that does not affect the function of the IC) allows the user to decide if he needs external protection means and how much effort has to be spent for external protection. 4.2 Single pin direct power injection Fo
47、r highest test selectivity, the RF power injected at the RF injection port is directly applied to a single pin of an IC (see Figure 2). A capacitor may be used as a DC block, while a resistor may be used for current limitation. By default, the capacitor value can be chosen as 6,8 nF, as specified in
48、 IEC 61967-4. The resistor value can be, by default, 0 . Other values up to 100 can be chosen if functionally required. Chosen R and C values shall be stated in the test report. NOTE When the series resistor is 0 , each input or output of the DUT will be loaded by the 50 of the RF power injection sy
