Reading
The oscilloscope (Fig 3.2) is basically a graph-displaying device - it draws a graph of an electrical signal. When the signal inputs into the oscilloscope, an electron beam is created, focused, accelerated, and properly deflected to display the voltage waveforms on the face of a cathode-ray tube (CRT).
Reading
A multimeter is a general-purpose meter capable of measuring DC and AC voltage, current, resistance, and in some cases, decibels. There are two types of meters: analog, using a standard meter movement with a needle (see Fig 3.1(a)), and digital, with an electronic numerical display (see Fig 3.1(b)). Both types of meters have a positive (+) jack and a common jack () for the test leads，a function switch to select DC voltage, AC voltage, DC current, AC current, or ohms and a range switch for accurate readings.

能力（技能）目标：
Let students know how to expression
1) What can be measured with a multimeter?
The meters may also have other jacks to measure extended ranges of voltage (1 to 5 kV) and current (up to10A) there are some variations to the functions used for specific meters.

课后作业布置：
Translation:A signal generator converts DC to AC or varying DC in the form of sine waves, square waves, triangle waves, or other types of voltage waveforms（Fig 3.7）. The signal generator is used to inject a signal into a circuit or piece of equipment for troubleshooting or for calibration. Some generators may be used for audio, RF, or higher frequencies, whereas others have overlapping frequency ranges. All generators will have a function switch, a frequency range switch, and a fine adjustment control for selecting a specific frequency, an amplitude control for varying the peak-to-peak output voltage, and output terminals.
