| The assumption is made that the reader has some familiarity with the ADALM2000 Lab hardware and Scopy software system before starting these lab activities.

| Remember, not all transistors share the same terminal designations, or pinouts, even if they share the same physical appearance. The order of some types is CBE (base is center lead) and BCE (collector is center lead) for others. This is very important when you connect the transistors together and to other components. Be careful to check the manufacturer's specifications (component datasheet). These can be easily found on various websites. Double-checking pin identities with a multi-meter's "diode check" function is highly recommended. | Remember, not all transistors share the same terminal designations, or pinouts, even if they share the same physical appearance.

| Learning to mathematically analyze circuits requires much study and practice. Typically, students practice by working through lots of sample problems and checking their answers against those provided by the textbook or the instructor. While this is good, there is a much better way. You will learn much more by actually building and analyzing real circuits, letting your test equipment provide the "answers" instead of a book or another person. For successful circuit-building exercises, follow these steps: | Learning to mathematically analyze circuits requires much study and practice.

| One way you can save time and reduce the possibility of error is to begin with a very simple circuit and incrementally add components to increase its complexity after each analysis, rather than building a whole new circuit for each practice activity. Another time-saving technique is to re-use the same components in a variety of different circuit configurations. This way, you won't have to measure any component's value more than once. | One way you can save time and reduce the possibility of error is to begin with a very simple circuit and incrementally add components to increase its complexity after each analysis, rather than building a whole new circuit for each practice activity.

| The common convention is that a typical silicon BJT base–emitter diode drop, ''V<sub>BE</sub>'', is 0.65V and a standard general purpose silicon diode drop is 0.6V. Other conventions use 0.6V or 0.7V for one or both. These are highly dependent on the manufacturing process used and the physical size of the components. The results you measure in the laboratory will most likely be between these values. Diodes and BJTs implemented on the same integrated circuit (i.e., on the same silicon die) may have equivalent characteristics. That is, the diodes and transistors will be more closely matched. Matched components are convenient to use in many circuit designs. We use discrete elements in most of these activities, and so it is not possible to match components unless they are all fabricated on the same silicon die. In the laboratory, a diode-connected transistor, with its base shorted to its collector may match the base–emitter characteristics of another transistor of the same type better than a simple diode. | The common convention is that a typical silicon BJT base–emitter diode drop, ''V<sub>BE</sub>'', is 0.65V and a standard general purpose silicon diode drop is 0.6V.
