P. USING NEAR FIELD PROBES FOR EMI EMISSION DIAGNOSIS In formal EMI certification testing a receiving antenna is located 8-10 meters from a DUT in either an EMI chamber or an open field site. Testing is designed to measure the emissions radiated from a DUT from any angle. Emissions can come from the top, bottom, right or left hand side of a DUT. This is shown in figure 1. Figure 1, open site EMI test In figure 1, a DUT is placed on a rotatable table and a height-adjustable receiving antenna is located 10 meters from the DUT. The antenna output is connected to a spectrum analyzer which is located in a shielded room. A perfect ground is needed to ensure an isolated environment. During measurement, the table will rotate 360 degrees so that the antenna receives omni-directional emissions. As the antenna is also vertically adjustable, emissions can be measured from various angles. However, EMI testing results can not distinguish where on the DUT the emissions were generated. When the emissions are too strong and fail to pass regulations, the source needs to be suppressed and thus has to be identified first. Near field probes are used to find the source of emissions on a DUT. The GKT-006 is a near field probe set which is used with a spectrum analyzer (in most cases) to detect E or H fields. The detection is accomplished by holding the probe and moving it around a DUT as shown in figure 2. When the probe is moved to the vicinity of the source, the E/H field will be inducted through the probe, showing the measured strength on the spectrum analyzer. The emission source can be located accordingly. During the operation, the probes (two loop and one stub probe) are used by means of "on-direct touch" so the probes will induct the E/H field. The probes are insulated with plastic so that short circuits to the DUT are avoided. Different types of probes are chosen to fit different frequencies and DUT shapes. Figure 2, moving the probe around the DUT The tip probe is a direct touch probe which allows the probe tip to directly test the circuits. Even though there is no ground connection to the probe the FR signal can still be measured for spot testing and location measuring. GKT-006 probe set contains four types of probes, two adapters and two cables. With these probes connected to a spectrum analyzer, the EMI emission source of a DUT can be located easily. The probe set is a very efficient tool for diagnostic purposes. Troubleshooting and pretests on a circuit can be performed prior to sending to an EMI Laboratory. B11
