5 F. PASS/FAIL JUDGMENTS G. TRIGGER FUNCTION The Pass/Fail Limit function is convenient for quick inspections of repetitive measurements. This function is especially helpful for the efficiency and productivity of production line testing. After setting high/low limits to create Pass/ Fail templates, the can quickly determine whether the waveform of an input signal is within the specified range (Pass) or not (Fail). The extensive triggering features add very flexible yet powerful triggering capabilities to the. Trigger source, mode, delay and frequency can be fully configured to isolate the right trigger conditions. H. AUTO SEQUENCE MODE I. SPLIT-WINDOW DISPLAY IN LIVE MODE Automatic Sequence feature offers a special functionality that frees you from complex programming; you can configure ATE test programs with the without going through software programming processes. After editing the auto sequence sets through the front panel, you can easily run different measurements in series (by a single key press) or carry out all the test sequences step by step. The split-window display allows one signal to be displayed in two different measurement modes or settings. Importantly both windows continue to be updated in the real-time regardless of the measuring modes. This feature is especially useful when measuring harmonics. J. THREE-TRACE INDEPENDENT DETECTION K. STATUS INFORMATION PRESENTED BY ICONS The is able to display three traces at once with various signal detection modes such as: peak, average, and sample. The other useful trace functions include trace math operations using the stored traces. Breaking away from traditional spectrum analyzer interfaces, the has adopted status icons to clearly show the current instrument status. The intuitive icons help you grasp the current conditions immediately. As all the status icons are clearly displayed there is no need to worry about other functions or settings which might cause measurement errors. B9

7 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
