2. Introduction:
A laboratory is a facility that provides controlled conditions in which scientific or
technological research, experiments, and measurement may be performed.



OBJECTIVE
In this lab you will learn how to properly operate the basic bench equipment used for
characterizing active devices:
1. Oscilloscope (Agilent MSO6032A),
2. Source Measure Unit (SMU) (Keithley 2430),
3. Function generator Agilent 33220A, and a
4. Bread board.
You will use these tools to characterize three simple resistive circuits, perform theoretical
circuit analyses on them, analyze the results, and present your findings in a concise,
organized lab report.

3. Equipment of lab:

4. Balance

an instrument for determining
weight
Beaker

used to hold liquids
Bunsen burner

used to heat substances

5. buret
