Document Summary
Purpose: construct a transistor curve tracer, and to use the transistor curve tracer to measure the characteristics of npn transistors. To apply the principles developed in the experiments performed so far to. For all procedures, connect the figures in the lab manual and record the output using the scope. Procedures: (all figures are on page 6 of this report: after assembling the circuit and making necessary scope adjustments the following graph was recorded. Lab session 11 transistor curve tracer: replace the transistor with a diode and plot the graph. After replacing the transistor in figure 1 with a diode the following graph was recorded. This graph shows that the diode allows current to flow once the voltage reaches ~0. 7v. Lab session 11 transistor curve tracer: after all previous steps were completed the transistor from procedure 1 was tested using the tektronix 571 curve tracer. The values or the tektronix 571 curve tracer are similar but beta is slightly different.
