Lab 1

Outcome of this lab:
1. Be familiar with the lab equipment.
2. Be able to edit your webpage and report your lab results to the website.

**If the function generator (FG) is running in the '50 ohm' mode, the FG has a 50 ohm output impedance internally. The displayed Vpp on the FG is only half of the signal that outputs. You need to use a 50 ohm resistor to bridge the Positive and Negative outputs of the FG to bring the output signal back to normal. This problem can be ingored if you turn the FG into the 'HZ' mode.

Instructions:

1. The DC (direct current) Power Supply
In the following figure, you will find the power supply (voltage supply or voltage source) in Fig. 1a, the 'Banana cable' in Fig. 1b, and the connection between the cable and the power supply in Fig. 1c.

Fig. 1 The DC power supply

Keep in mind that we usually use the 'Red cable for the positive and the 'Black cable' for the negative.

1.1. Deliver a +5 V and a Ground line to a breadboard.  Take a picture of the board and the voltage reading (on the power supply) for the lab report.
1.2. Deliver a +5.2 V and a Ground line to a breadboard.
Take a picture of the board and the voltage reading (on the power supply) for the lab report.

2. The Multimeter
The cables are shown in Fig. 2a, the multimeter is in Fig. 2b, the connections for voltage measurement is in Fig. 2c, for current measurement is in Fig. 2d. Always use the 'Red' one for positive and the 'Black' one for negative.

Fig. 2 The multimeter

2.1. Measure the 5 V on the breadboard and take a picture of the voltage readings on the multimeter.
2.2. Build the following circuit on a breadboard, measure the current flow in side the circuit. Take a picture of the current reading for the report.

3. The function generator (FG) and the oscilloscope
Fig. 3a shows the cable for the FG, Fig. 3b shows the FG, and Fig. 3c shows the connection between the cable and the FG.

Fig.3 The function generator

Same as the power supply, if you don't press the 'on/off' button, the voltage waveforms won't be delivered to the output terminal.

The oscilloscope:
This is the most complex equipment among these four, we will cover more about it through the semester. Make sure you use the correct cable for the oscilloscope:
