Lab Report - Lab 2: Introduction to TIMS

Introduction

The purpose of this lab is to introduce the use of the TIMS machine and to simulate a simple signal function. Additionally, the lab provides practice in using the signal analysis software. The lab provides a baseline for how to go about future lab procedures.

Procedures


Part A: PC-MODULES CONTROLLER and PicoScope
The first part of this lab involved utilizing picoscope for the first time to read a simple waveform. The waveform was generated by the TIMS unit and was created by putting connector wires from ChA to the 2kHz MESSAGE on the MASTER SIGNAL module and putting another wire from ChB1 to the 8.3 kHz SAMPLE CLOCK shown in the figures in the lab procedure. The lab gave instructions on how to read in these signals through picoscope by turnign on each signal. Below is the result of showing both signals in picoscope.  Additionally, the lab demonstrated how to use spectrum mode in picoscope and how to shacne the spectrum range and how this range effects the signal shown in picoscope. The screenshot below shows the result of the same signals from above shown in spectrum mode.
Part B: Triggering
The second part of the lab involved using the trigger parameter in picoscope. The lab demostrated how to use triggering to stabilize the signal shown in picoscope. Additionally, the lab the difference between using a rising and falling edge trigger and what that does for the output in picoscope. Triggering is an essential for being able to get a signal to show up in a desired fashion.
Part C: TIMS S&S SFP
Part C of the lab involved using the TIMS S&S SFP software. This software is a way to get premade signals into picoscope utilizing the ARB1 and ARB2 TIMS modules that connect the unit to the lab computer. Once the computer is connected to the TIMS unit, the SFP software can be used to generate signals for each lab meeting. When connected to picoscope, the same signals shown to be generated in the software are shown in picoscope. This tool is useful as it allows for any signal to be input simply via software.
Part D: SFP Control of Triple ADDER Gains
Part D of this lab involves utilizng a TIMS unit module that adds can add three signals together. It is important to note the slot of the TIMS unit that the module is placed in so that the software can interact witht hte module properly. I placed my triple adder in slot 5. The procedure for part D involves interconnecting the triple adder with a 2kHz MESSAGE signals and the 8.3kHz signal into the input of the triple adder. ChB1 is the connected to the output of the triple adder, making ChB1 the resulting sum of the two input signals. Additonally the SFP software is used in this process when modifying the gain of either waveform. The screenshot below shows the result of the two signals being added together and the gain of the signals being modified.

Conclusion


What did you enjoy about this lab?
I enjoyed the hands on aspect of this lab. It was nice to be able to see where the signals were coming from and how they were output into the software.
What didn't go well in this lab
Something that did not go well was figuring out what the picture was showing. I missinterpreted the picture and had to ask for help from my TA. She showed me that I can stack the wire plugs on top of each other to connect them together.
How would you improve the lab experiment for the future classes?
Something that could be improved is the clarity of the pictures in the lab write up. I think they could have indicators as to what part of the picture the procedure is talking about.
