Lab 1

Lab #1

Getting Started: Instruments

and Measurements

1. OBJECTIVES

The primary objective of this lab is to familiarize you with the laboratory equipment and software programs you will be using this semester. Additionally, you will make some basic measurements. A lab report will be required for this session.

2. COMPONENTS AND INSTRUMENTATION

– Multimeter

-100 Ω resistors

– DC power supply, for 5 VDC

– Waveform Generator

– Oscilloscope with probes

– Computer with Multisim software for computer simulations

– Wire, alligator clips, and a breadboard

  1. Use the function generator to generate a sinusoidal wave with amplitude 5V and frequency 1000Hz.

   Verify the waveform with the multimeter and the oscilloscope.

   Record the multimeter reading.

   On the oscilloscope, display the waveform frequency, peak-peak value, and RMS value along with the waveform.

   Explain why the value displayed by the multimeter is not equal to 5V.

  1. Use the function generator to generate a square wave with MAX 5V, MIN 5V, frequency 1000Hz, duty cycle 20%.

Use the offset to achieve the maximum and minimum values.

On the oscilloscope, display the waveform along with its frequency and peak-to-peak value.

3. Use the power supply to generate 5V DC.

A. Construct the circuit given in Figure 1 of Circuit Diagram and Graphs section. Calculate the voltage of resistor R3.

B. Keeping the 5V DC source, measure the voltage of R3 with the oscilloscope and save the waveform along with its MAX and MIN values.

C. Replace the 5V DC with a 5V 60Hz sinusoidal wave generated by the function generator. Measure the voltage of R3 with the oscilloscope and save the waveform along with its frequency, peak-to-peak value, and RMS value.

D. Perform B and C in Multisim and save the diagram and results.

Lab report is individual and Analysis part should be on your own words.

The Lab report must include all lab procedures, all the observations from hardware and software simulations, and a detailed analysis.
