1. Title: Equipment and Edit Your Webpage

2. Introduction: This lab follows the procedures required to use the DC power supply, the function generator, the multimeter, the osciliscope, and all of their respective cables.

3. Materials and Methods:  Both the DC power supply and the multimeter are powered on. The power supply cable is  plugged into the first "battery" terminal. The multimeter cable is plugged into the first channel on the multimeter. An output of 5v is selected on the DC power supply. The power supply cable is connected to the bread board and the bread boards ground and positive wires are probed by the positive and negative multimeter probes (Figure F1, F2). The power supply is set to 5.2v and the probing process is repeated (Figure F3,F4). The multimeter is connect to the 5v power supply (Figure F5). Two 1k ohm resistors are added in series to the bread board. The circuit is broken by disconnecting one end of the last resistor from the ground pin on the bread board. The multimeter is set to current detection, and the multimeter's probes are used to bridge the gap between the open end of the resistor and the open ground pin (Figure F6, F7). The function generator and the osciliscope are powered on and the respective cables connected. The osciliscopes probes are connected to the standard signal on the osciliscopes bottom right. The amplitude, frequency, and signal type are recorded (Table 1). The function generator is set to 5 Vp-p, 1kHz. The function generators cable is connected to the bread board's positive and ground terminals. The curerent generated by the function generator is then probed by the osciliscope.

Task 3.2

The function generator is set to sine 1kHz, connected to the bread board, and the osciliscope is used to probe and analyze the signal from the signal generator.
