The old school method of modifying your registry is through the Registry Editor application in Windows. Registry Editor has been around for some time now, though very likely you haven t ever used it. As I ve said before, editing your registry is some pretty serious business; if you re not comfortable with doing it, or assessing the potential risks, don t do it. The Windows Vista Registry Editor is exactly the same as the version shipped with Windows XP, as shown in Figure 28.1.

may have used the equipment for a specialized use the day before and failed to restore the instrumentation setup to its original state. The following is a list of potential problems from instrumentation one should be aware of: (a) Incorrect bandwidth selection on the receiver or spectrum analyzer. (b) Improper detector (peak, quasi-peak, average) (c) Inappropriate scan time for the range of frequencies to be examined too fast or too slow (d) Video filtering applied that may affect the amplitude of the measured signal (e) Overload of the front end of the receiver or spectrum analyzer by out-ofband signals, including 50/60-Hz components (f) Vertical linearity affected by incorrect switching steps or not set at the correct reference level (g) EMI and ambient signals added together to create a false reading. Narrowing the bandwidth will help separate these signals into their discrete components, which can then be measured individually. (h) Insufficient sensitivity of the receiver relative to ambient background noise (i) Broadband noise preventing detection of narrowband noise spikes

Many analog circuits rely on the property of technology that identical layout structures are also identical in an electrical sense. The electrical quantities voltage, charge, or current are derived from basic components like resistors, capacitors, transistors, and units of time. The equality of the electrical quantities depends strongly on the reproducibility of the basic components. Deviations in the reproducibility of the basic components are described by "systematic mismatch" and "random mismatch": unwanted differences in the effective value of equally designed components. 15-21 Systematic mismatch (offset) is defined as the nonzero mean value of the difference in value between many pairs of components, while random matching refers to the stochastic spread c (see Fig. 11.8). Systematic and random mismatch in the basic components is caused by deviations in the fabrication process, deviations in the electrical conditions during use, or unequal timing moments. Mismatch will show as a Gaussian distribution if the source of mismatch is composed of many mutually independent events such as implantation of ions. For electrical matching of the basic components, the voltages on all the elements must all be the same (equally affected by voltage drops in power lines, leakage currents in diodes, etc.), the substrate coupling must be the same, parasitical components must be matched, and so on. In extended analyses also electrically derived effects must be considered, such as, heat gradients due to dissipation, aging of components, and threshold drift due to hot-carrier effects. Especially in highfrequency A/D conversion, the "conversion units"are based on the reproduction of physical basic components, while low-bandwidth converters rely strongly on timing accuracy. Examples of systematic mismatch in basic components due to lithographical and chemical effects in the fabrication process are

Windows 2000 domain trees are joined to another domain tree during the Active Directory installation process. As discussed in 12, Implementing Administrative Control Over Directory Objects, during the installation of a new Windows 2000 server the following options are presented:

Figure 17-8: The Toolbox If you have code snippets that you use across many projects, or there is code that you don't want to type every time you need it, you can add that code to the Toolbox. My goal in life is to write as little code as possible, so I have tons of code snippets stored in the Toolbox. To add code snippets to the Toolbox: 1. In the Code window, highlight the code you want to add to the Toolbox. 2. Drag the selected code to the General tab. 3. Right -click on the Toolbox and select Rename, and give the newly added code snippet a meaningful name. You can do all Toolbox customization with a right -click, so go ahead and look at the menu options available when you right-click on the Toolbox.
