ELEC 105 Lab Assignments

ELEC 105 - Lab Assignments

Week 1 - Measuring Voltage

Be sure that you have read and understood the introductory lessons on measurements and measuring voltage before you come to lab.
Read the lessons on how to use the Fluke Hydra Data Acquisition Unit (DAU) for voltage and temperature measurements.
Do these lab exercises:

Week 2 - Sensor Dynamics Data Collection

Be sure that you have read and understood the introductory lessons on measurements and measuring voltage before you come to lab.
Be sure that you have read and understood the material on time constants.
Do this lab exercise:

Temperature Sensor Characteristics - Getting Time Data

You will need these files to take measurements and store the data in a file:

NTempsHydra.vi - to measure temperature from the Hydra
NVoltsHydra.vi - to measure voltage from the Hydra.

Analyze your data and do that for homework to hand in Monday. Click here for the detailed assignment.

Week 3 - Learning About the Oscilloscope and Function Generator.

An Introduction to the Oscilloscope (and the Function Generator)

Oscilloscope + Function Generator Experiment

Another sensor - the Pressure Sensor (and you will learn about some auxiliary equipment including a pump motor and a flow rate sensor.

Pressure Sensor Experiment

Week 4 - An Introduction to Frequency Response/Filters

Filter Appreciation Day. This exercise will let you experience a filter, and will introduce you to some of the reasons you need to know about op-amps.

Week 5 - Second week on requency Response and Filters

Going back to the pressure sensor, we will look at some details of that signal.

Do not disconnect the isolation amplifier from the filter. Use the same circuit for the portion of the lab on "Filtering a Sensor Output".
Filtering a Sensor Output

Here is a link to some questions on the filter labs.

Week 6 - Exploring Operational Amplifier Filters

The Op-Amp Subtractor

Week 7 - Exploring Fourier Concepts

Fourier Components in a Signal (Square Wave)

Week 8 - Exploring Fourier Concepts - 2

Measuring Fan Speed. You measure fan speed by interrupting a light signal, and we hope that you see the light.
Getting the resonant frequency of a bar. (That's a steel bar, not the other kind.)

Week 9 - No Lab - Fall Break
Week 10 - LabVIEW Introduction

Week 11 - Moving Toward a Useful LabVIEW Thermometer.

The LabVIEW Thermometer - Part 1

Week 12 - Modifying the LabVIEW Thermometer - Under Construction

You will save data to a file that can be loaded into a spreadsheet, and you will build a LabVIEW file that measures and displays temperature.

Writing Data to Files in LabVIEW. This exercise will get you started writing data to a file. Do the exercise described in the link, then modify your LabVIEW Thermometer to include saving your data to a file. Click here for the specifications for your vi.
Word length (# bits) in an instrument. Do only the portion for the Hydra (Digital Voltmeter).

Week 13 - Data Across the Network - 1

Remote Viewing in LabVIEW. In this problem, when it says to "go to a different computer", you may have to go somewhere else on campus. There are several computer labs in Dana that you can get to. You want to be able to view your application running across the network. This way is the simplest way to get data across the network as long as you don't want to transmit any data the other direction.

Network data transmission - An introduction to using TCP/IP for information transmission. This link takes you to a general page for both the server and the client. You should work on the server today if time permits. Click here for a slightly more detailed description, including making a sub-vi.

Weeks 14&15 - Data Across the Network - 2

Network data transmission - This is the server-client lab. Today you should work on the client vi in LabVIEW.
Click here for some questions on this experiment - the same questions as before.
