ENGR201 Lab 2018 Fall
Lab 1
Lab equipment and edit your webpage for your lab report. Due Sep 3, Monday 10 pm. 
Outcome of this lab:
1. Be familiar with the lab equipment.
2. Can 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 out signal back to normal. This problem can be ingored if you turn the FG into the 'HZ' mode.

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

Remember we usually use the 'Red cable for the positive and the 'Black cable' for the negative.

Turn on the power supply, try to tune it to different voltage outputs by directly press the buttons for the demanded voltage output or turning the knob ot the top-left corner.

Press the button 'On\Off' to deliver/block the voltage to the output terminals.

2. The Multimeter:
The multimeter has its own cables, do not mess it up. The cables are 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.

3. The function generator (FG):
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.

4. 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:

(Take pictures of the results use you smartphone for your lab report)
1. Build a circuit on a breadboard as follows:

Give Vin 5V, and mearsure Vout use the multimeter.
2. The same circuit, give Vin -5V, measure the Vout
use the multimeter.
3. Change the voltage supply to +-5V, and test the voltage at Vout use the multimeter.
Explain how the following connection can provide +-5V to the circuit.

What is the current flow in this circuit? Use the multimeter to test this.

** Report your results (with figures and texts) on the website.
