Instrumentation Lab COURSE INFORMATION
Welcome to the Physics 111 Lab—Instrumentation Lab (Previously BSC) course! During a regular semester, the Instrumentation Lab is a fifteen-week course that requires two to three, 4-hour afternoons of lab time and two, 1.5-hour lectures twice a week, on average, in addition to outside reading, analysis and writing. The course covers basic electronics (filters, diodes, transistors, op-amps, analog & digital circuits, D/A conversion, and LabView Programming, etc.) and measurement techniques with an approved Final Project of your choice. It will also teach you how to use equipment found in a typical physics research laboratory and how to write scientific reports.
Before taking advanced laboratory section of the 111 Lab, you must take Instrumentation Lab (physics 111A) unless you have taken an equivalent electronic course (e.g. from the EECS department or physics 111 professor approval).
Some students find that the 3-unit Instrumentation course takes more time than two 4-hour afternoons. This is an upper division physics Lab course and moves very quickly! Students completing Instrumentation Lab last semester estimated that the course takes between 12 and 15 hours each week total. Please plan your time accordingly.
The course is organized around the lab assignments. You'll be doing them continuously. Each lab has a write-up that you work through with a partner. See below for more hints on how to do that and how to get the most out of it. At the end of each lab, there's an assignment to be turned in. Some of these are formal lab reports, some are informal (shorter reports), and sometimes you just hand in a copy of your lab notebook. Except for notebook copies, all materials handed in must be typed. All assignment reports turned in online.
Pre-labs must be done in advance. They should be at the front of that week's section in your lab notebook. You need to show them to a GSI and get them signed off before the start of your reserved lab period.
Late assignments will be subject to a penalty per day late. Extending your assignment due dates without penalty would require exceptional circumstances. On those occasions, approval must be in advance and via email from the Professor and must be included in your report. Past one week, if the lab has already been graded it will receive a grade of 'F' equal to zero. You must still submit all assignments in order to pass this course.
Students must complete all required work and turn it into the 111 Lab in order to pass the course. Any missing work will result in a final grade of "F" for the semester. You must turn in all labs, even if they're late, to pass this course.
The last assignment is a project of your own development, with professor approval. We'll provide more information on that as the course goes along. You'll submit a proposal, discuss it with the instructor, then build and debug your project. At the end of the course, you'll demonstrate it and write a typed written final lab report and upload a PDF to Bcourses .
Computers in the Physics 111 Lab:
You must be enrolled in the course and have a valid CalNet ID Login name to log into the computers. Save all of your data and files to the DeskTop or My Documents Folder; everything else will not be saved or backed up. You also want to save your files & data to your own 8GB USB thumb drive. Experiment and equipment information is located on the 111-Lab Share folder on your network drive from within the 111-Lab in “My Computer” on each computer or from the Physics 111-Lab Library site.
Both the University and the 111 Lab staff take the subject of academic honesty very seriously. Please make sure you understand completely the following and ask questions if ever in doubt:
"All data that you present in your reports must be your own. All written work that you submit, except for acknowledged quotations, is to be in your own words. Work copied from a book, from another student's report, or from any other source will, under University rules, earn the student a grade of 'F' for the semester, and possible disciplinary action by the Student Conduct Committee."
Note on Working Together
Research in physics is facilitated by close cooperation and collaboration among those involved. Indeed, if scientists did not share results and argue over interpretations, new discoveries and insights would be much fewer and further between. You will find in the 111 Lab that you learn a great deal from working and talking with your classmates, especially your lab partner. However, as in other courses, each student will be given a grade based solely on his or her individual achievements. Each student must turn in his/her own lab report, in his/her own words. This requirement is not intended to reduce cooperation or discussion in or out of the lab. On the contrary, we encourage you to discuss your results with other students and to try to make sense of them together. The final product, however, must be your own work.
What is not acceptable? In general, use common sense. Raw data and good ideas should be shared with your classmates, but text, analysis, graphs, figures, and derivations of equations should be completed alone. If you have any questions, please ask the lab staff.
Plagiarism will result in a final grade of "F" for the course.
Course Material Fee
Physics 111A Instrumentation students are assessed a Course Materials and Service Fee (CMSF) of $175 to cover the cost of expendable supplies and materials used in the course. These fees are collected after the fifth (5th) week of classes and will be included in each students’ CARS (Campus Accounts Receivables System) statement. Income from the CMFS is kept in a separate account that is used only for the purchase of supplies and expendable materials for Physics 111. Equipment purchase and repair, computers, and staff salaries are paid for by the Physics Department, not by student CMSF.
You can sign out a VB-108 type breadboard and keep it for your own use from the back wall of the lab. That lets you build a circuit one day, and still work on later days. You can keep the breadboard in a slot in the lab (recommended; pieces tend to fall out when you transport them) or take it with you.

Final Project ***
Friday November 16
Friday December 14**
The regular lab reports are all of equal weight, while the final project report is worth 25% of your grade.
You will lose 10% per day for late reports. Any lab turned in one week after the due date will receive no credit. Please note, though, that in order to pass the course, all lab reports must be turned in. Any potential exceptions for late lab reports must go through the professor.
- For every lab, each GSI will pick one or two problems at random to grade on a coarse scale for a total of 2pts per GSI.
- Your signatures will be worth a total of 5 pts.
- Each lab will be graded out of a total of 15 pts.
ALL lab assignments must be turned in to pass the class,
Scoring a zero (perhaps by turning in a short report late) means lost points, but not turning in a lab means automatic F for the course.
Don't waste precious lab time on lab write-ups. Get it done outside of class.
- Exceptions may be made for extraordinary circumstances at the Professor's discretion. This is much more likely if you contact the professor before the deadline rather than after.
We do not distribute solutions, because the lab questions do not change semester-to-semester, but rubrics will be made for all graded problems.
Regular Lab Report Guidelines
Lab reports will be submitted in pdf format online via Gradescope by 11:59pm on the day that they are due (see due dates on the website), and adhere adhere to the following quidelines:
- The reports can be typed or very neatly written (you will be marked down if we have trouble reading your answers). Your favorite word processor is fine. However, this is a good opportunity to learn how to use Latex, if you haven't already. Overleaf.com is a good (free) front end for this purpose. And http://www.texmacs.org/tmweb/home/welcome.en.html is a Latex compatible WYSIWYG processor with a relatively quick learning curve (although, we don't know how well it is being maintained).
- The reports do not require an intro/conclusion. Thus, the lab report consists of numbered responses to the lab questions, any plots/figures corresponding to the analysis within, and a signature sheet (see below). Responses to the pre-lab questions are not required in the lab report.
- The reports should include a title with your name and the name of your lab partner.
- Lab questions should be numbered and answered in the order that they appear in the manual. If plots are not on the same page as the question, reference their page number in the question.
- The reports should include a single signature sheet. The signature sheet can be any scratch piece of paper that includes all of the signatures required by the lab (including pre-lab signatures), clearly labeled. You can scan or snap a photo of this page and should include it at the end of your report.
- You do not need to include a writeup for any of the lab questions requiring a signature. You will be graded solely on the possession of the signature. But be aware, that several of these problems ask for things like plots, which should be completed before you ask a GSI to check you off. The idea here is that at some point a grader is going to go through your lab and check to see that you've received all of your signatures. So having them organized all in one place both makes it easier for the grader and also ensures that you won't get marked o for a missing signature that's buried somewhere within your lab.
- All quantitative plots should be generated using your preferred plotting software. Microsoft Excel can be used for this purpose, but you need to make sure that your plots are readable and properly labelled (axes, ts, etc.). One such program is http://www.sagemath.org/for quick plots (a Python front end for some commonly used math modules), which has a ton of easy-to-read documentation and examples. Also, everyone should have access to Mathematica/Matlab/Maple licenses through https://software.berkeley.edu/ and most of the GSIs are familiar with these, if you have any questions.
- Non-quantitative plots can be sketched, photographed or a screenshot of the scope can be captured. While you can use your cell to photograph the screen, we prefer you use the screensave option on the scope which will put an image onto a thumb drive. We are not too strict about this as long as the qualitative features can be discerned readily.
Final Project Report Guidelines
FInal project reports are complete reports with an introduction, conclusion, references, etc. The FInal project reports are graded by the professor. Full instructions will be distributed later.
*** Final Project NOTE: Submit online a 2 page or less proposal for your final project with a Circuit Diagrams and Block Diagrams on or before the bCourses Final Project Proposal Due date (Nov 5 or thereabouts for Fall 2018).
The final project proposal is the only instance in this course where you will submit identical work. For both the initial and revised proposals, please coordinate with your partner to submit duplicate proposals that clearly display your project title and lab partner's name.
Note: [It is not required to order special parts for the final project. Your grade will not go up if you order special parts. You can get a perfect score using just the parts in the lab. Your grade will go down a lot if you order special Op Amps, transistors, etc, without explaining why you need them.] Purchase your final project parts ahead of time including any other breadboards you will need. Ask professor if you need help.
NOTE: Please check out and keep the portable breadboards, VB-106 or VB-108, from the 111-Lab for yourself ( Only one each please)

Project Ideas: See the Lab 12 Manual
· Ask the GSIs or Professor for others if needed. Plan ahead!
**Inspection of physical Final Projects will be on or before the last four days of classes. See Professor for Details.
=>Every student must complete their own final lab write-up. (Due date and submission method TBD by professor) **
Final Project Information:
The last assignment is a project of your own development. We'll provide more information on that as the course goes along. You'll submit a proposal, revise as needed, then build and debug your project. At the end of the course, you'll demonstrate it and submit a written final lab report.
• Turn in a 2 page or less proposal for your final project with a block diagram and schematics of key parts. The idea is to focus on what you’re going to build, and show you’ve started thinking about how to build it.
•The professor will approve your final project proposals or engage you in a dialogue about how to improve them if needed.
There should be only one proposal per lab team. You will write it together, with both names on it.
The lab is open through the last day of class. Lab hours will be extended as needed see Professor. No work will be allowed in the 111 lab rooms after Friday. Please attempt to complete your project early, in case of unexpected delays.
There are two parts to the end of semester process.
- Evaluation: Your project will be evaluated in lab during the last week of the course. You will need to demonstrate your project to the Professor. There is no sign up for this process and projects will be evaluated in the order that they are declared complete. This process can get busy on Friday, so please get your project checked out earlier if possible.
This checkout procedure is similar to being quizzed about a lab section to get a sign off, except it will be more thorough. You should be ready to discuss the details of the design and performance of your project. All team members must be there at the time the project is signed off. It will be very helpful if you have a complete schematic for your circuit which you can refer to in this discussion.
- Final Report submission: You will individually write and submit your own final lab write-ups just as for the other lab reports. Please make sure to include the name of your lab partner and project at top of the front page of your report. The final report should be relatively short and concise. It should contain an introduction describing the goals of your project, a section describing the design and execution including metrics of performance, and finally a set of conclusions. If the performance of your proposal was less than optimal, please attempt to discuss how it could be improved. Please include a complete circuit schematic and a block diagram of any Labview code with your report.

Remember that your lab book should be a self-contained, stand-alone description of your laboratory experiments: when you look it over, say a year from now as you fondly remember your undergraduate days, it should make sense to you!
NOTE: You will probably need more than one of these lab books.
· When writing in your Instrumentation Lab Notebook:
· Use a pen. NO PENCILS PLEASE!
· Give the following information at the top of the lab write-up:
Your name Date
Your partner's name Station number
Week number and title of lab
· Record all of your data and observations in your notebook; don't use “scratch paper.”
· Record the settings and conditions under which the data was taken.
· Be as neat as possible. (Sections that cannot be EASILY read will not be graded.)
· Line out with a single line (e.g.
Ooops) anything written in error (data or text).
· Use a single large "X" to indicate any sections that you do not wish to be read.
· Use a straight edge to draw lines that are supposed to be straight (graph axes, column lines, etc.).
· Attach any loose sheets (e.g. semi-log graph paper) with your assignment.
· Pre-lab questions must be signed off by TA's before each lab.
· Your logbook should show a clear understanding of the Lab and the work that you did in the laboratory. It should not be longwinded, it should not include all possible details, and it should not be a scattergun approach.
In the lab
After the Pre-lab, you take data for that week's lab. You then present that in your report. Make sure that you:
· number the sections of your data so they correspond to the numbers in the lab manual.
· make tables clear and neat, and be sure to always label columns and include units and some estimate of uncertainties.
· answer questions posed in the "In the lab" section in the same section as your data.
· include circuit diagrams and figures showing the set-up. Any circuits analyzed, built or used should be diagrammed. If you have a digital camera, take lots of pictures, but you should still make diagrams in your lab notebook.
There are places marked in the lab where you are supposed to get a GSI signature. These are meant to let the GSIs check up on your progress throughout the lab. Therefore, you need to get your lab questions signed as you complete them. GSIs expect to see your circuits and signals so we can test them, not just your recordings in your notebook. Also, signatures are not an answer, they are just an acknowledgement that you completed the section. Explanations are still required.
Please start each lab with a section for the GSIs to sign all in one place.
Each lab contains “Questions” which refer to the data which you have taken in lab. Please number your answers. Extra information is fine, but don't bury your answer where it can't be found. Clearly set off the final results (e.g., box numerical answers) and, of course, always include units and error estimates. Compare your results with your expectations whenever possible.
You may wish to complete some of the questions while in the lab, rather than waiting until later (e.g. calculating amplifier gains, making plots, etc.). This is often a good idea but please indicate where you are completing one of the “Questions” by labeling it.
Graphs, tables and scope traces
Data plots and tables are often the easiest ways to convey information. All graphs must have a title and labeled axes showing quantities and units. Make all graphs large enough so that they may be easily understood. Graph families of curves or related functions on a single set of axes. Error bars are almost always required. Number all figures and graphs and include legends. If there are a lot of points, or if you need to fit the data to a theoretical curve, it is usually best to use a computer-plotting program to prepare the graph.
Axes should also be labeled on scope trace sketches, as should the heights and widths of its features. Basically, a sketch should contain enough information so that it can be used to reconstruct what is important in a trace. You may not know at the time what is important, so you’ll have to use your best judgment. It’s usually best to err on the side of completeness.
As this class is focused on getting experience building circuits and analyzing circuits, you do not need to do formal error analysis. Still, this is a physics lab, and some attention must be paid to the uncertainties in your data and analysis. Uncertainty estimates come from consideration of the measurement itself, not from the comparison of theory and experiment. In each case you want to ask yourself the following two questions:
· “What is the range of values for my measurement over which I can’t reliably state that one answer is better than the others?” This is roughly the statistical uncertainty (error), and it can always be easily assigned.
· “By how much might I actually be measuring something different from what I’m intending?” This is roughly the systematic uncertainty (error), and it may require more thought to quantify.
Only the dominant source or sources of error are important. One can only make a reasonable comparison between theory and experiment if the uncertainty in the result is known.
Acknowledgments and References
Indicate who your partner is and indicate which parts of the lab you did together and which you did separately. Reference any outside sources you used (text, friends, etc.); give credit where credit is due.
If there are any then the points for these are kept track of separately from the rest of the lab. In cases where your grade is just below a grading boundary, having done this extra work may boost you up to the next grade. The supplementary problems are often among the most interesting exercises, and they are not in general more difficult. If you do not have time to do them, you should at least read them over.
Your report should be type written at a level such that one of your classmates with the level of understanding that you had before you started the Lab could pick up your report and understand what you did, what electronics is illustrated, and how good your results are.
TIPS FOR SUCCESS
· Get started early. Reports always take longer to complete than one expects.
· During the lab session, make estimates for measured quantities to see if what you are doing makes sense. This will save you return trips to the lab!
· Be neat. Understanding the material is only half your task. Your presentation must be clear enough and easy enough to read that the reader can be convinced of your mastery.
· Watch your units. Confirm that measured quantities have the appropriate units. A unit-less answer is meaningless.
· Define variables in equations. What is obvious to you may not be to the reader.
· Locate experimental uncertainty. Nothing elaborate is expected but be aware that errors (uncertainties) do exist. Identify sources and estimate magnitudes of error.
· Proofread. Check for both simple and conceptual typos. Compare your results to theoretical predictions and to the component specifications. Order of magnitude estimates are often sufficient for checking results.
· Ask questions! The only dumb questions are the ones that aren't asked.
· Don't waste time in the lab. Time management will be crucial in the lab and if you are getting ahead, stay ahead. If you are done with the lab 2 hours early, start the next one. Holidays and sickness can throw you off permanently if you don't take advantage of all the time you have.
HELPFUL HINTS FROM GSI's: How to ace your lab report.
You need to get a signature from your GSI for the Pre-Lab questions before you can get a signature for any questions marked with a pen.
You also need to get GSI's to sign the problems that are marked with a pen.
On your Lab report, you need to attach an original or copy of these signatures.
Without these signatures, you will not get credit for these problems.
Try to do all the problems in the Lab write-up.
GSI's are not going to grade all of the problems. Part of the report will be chosen for grading. You will not know in advance which problems are graded or not.
· It is usually better to turn a lab in somewhat incomplete than to turn it in late, losing points and time.
· Exceptions may be made for extraordinary circumstances at the Professor's discretion.
· Please turn in the evaluation for each lab. Please put at least 10 minutes of thought into it; simple yes or no answers do not help us. (Would the evaluation you turned in help you if you were the one trying to revise the lab write-ups?)
Final Advice: Here are some comments that will make your 111 Instrumentation Lab experience much easier and enjoyable for you (and less time consuming). First of all, do not simply think you do not have homework because this class is a lab.
· Before the lab: It will help you tremendously if you read and understand the lab write-up before you come in to start the lab. Look over all the questions, including the pre-lab questions, and determine anything you do not understand. This would also be a good time to write your introduction since now you know what the lab is about.
· In the lab: When you come in on your first day, you can discuss the pre-lab questions with the GSIs and answer them. This would also be a good time to discuss anything you are not clear about. In addition, try to follow directions; you could lose points by simply not answering the questions fully. Finally, if you have any doubts about anything, please ask a GSI.
How to Use the Lab Write-Ups
Read the write-ups before coming to lecture. The labs are divided into four sections: the Pre-lab questions, which should be completed before coming to the 111-Lab, Background materials, In Lab work, and Analysis. Not all labs have all sections. Be sure you understand the background material and have answered all the pre-lab questions before you come to class. The Analysis questions can be answered at home after you finish the labs. Ask questions if you are confused…electronics is a difficult subject that is new to most students. Don’t be dismayed if some of the other students seem to be faster than you; probably they just have some previous experience.
The write-ups are available from the 111-Lab Instrumentation Lab WEB site at:
Circuit schematics and some analysis programs can also be downloaded from the site.
The lab write-ups are not intended to be used on their own. Make sure you read the assigned reading.
Take a quick look at the glossary before you begin this course. There are too many terms there for you to memorize their meanings all at once, but knowing which terms are defined will help you later in the course.
The labs contain several ideograms:
|Means do this before you come to the Physics Instrumentation Lab.|
|This means that you have to have the results of the indicated problem checked and signed off by a GSI.|
|Indicates that the adjacent schematic has a Multisim model.|
|*||Denotes an extra credit problem.|
The Instrumentation Laboratory is the first semester of the Physics Departments' advanced laboratory class, Physics 111, required for all physics majors. The class starts with 11 labs, and ends with a final design project. The labs progress from basic instrumentation to frequency dependent components, transistors, op amps, and computerized data acquistion and control. Each lab takes approximately two afternoons to complete; approximately one lab is due each week.
Many faculty and staff members have worked on the lab experiments and manual, including Joel Fajans, Bruce Birkett, Sumner Davis, Roger Falcone, Kam Biu Luk, David Weiss, Bob Jacobsen, Don Orlando, Howard Shugart, Sudeep Dutta, Damon Brown, Nate Belmore, and the Electronic Shop Staff.
In 1996, I started the major revision on the labs and the manual; I am grateful for the patience of the students during the semesters that the lab was being revised: Joel Fajans [(Revision Summer ’02, Jim Siegrist), (Revision Spring '14, Bob Jacobsen), (Revision Spring '16, Joel Fajans)
