Contents Introduction & Test Procedure Page 3 Test Procedure (contd.) Page 4 Peak-to-Peak voltages & Frequency explained Page 4 Conclusion Page 4 Results Pages 5-10 Introduction The purpose of this laboratory exercise was to introduce the student to the techniques of using an Oscilloscope, a test meter, a waveform generator and a spectrum analyser. Three waveforms were examined; the first was a SINE WAVE; the second was a SQUARE WAVE; the third was a TRIANGULAR WAVE. The Oscilloscope was also used to make measurements in the TIME DOMAIN and the spectrum analyser in the FREQUENCY DOMAIN. Test Procedure Oscilloscope measurements: We connected the output of the waveform generator to the A channel of the Oscilloscope and then the Oscilloscope setting was adjusted so that it would display the waveform as a sine wave.
Simultaneously we adjusted the frequency of the generator to 1 kHz and the output level of the generator to 1 V r. m. 's. using the test meter and then adjusted the Oscilloscope display so that two to three periods were shown. r. m. 's. = route mean squared, this is the equivalent to a direct current. Vrms. = Vmax 2 Vmax = 2 x Vrms = 2 x 1 = 1.44 Therefore Vpp = 2.825 pp = Peak-to-Peak Analyser Measurements: 1) Time Domain: Next we attempted to use the analyser to measure the time waveform. We connected the generator output to the input of the analyser and pressed the time button. We used the frequency buttons to adjust the scale on the time axis and we used the AMP buttons to adjust the voltage scale. It was also possible from here to make further voltage and frequency scale adjustments using the menu available on the display.
These results were recorded and are documented in this report. 2) Frequency Domain: By pressing the SPECT button we were the able to observe the signal spectrum. We adjusted the frequency and zoom so that the horizontal scale occupied at least 3 kHz centred on 1 kHz. Peak-to-Peak Voltages This is a measurement taken between the two maximum points of Amplitude within one cycle. (The Amplitude is the instantaneous value of signal at any time and for electromagnetic signals the amplitude is measured in volts). e.g. The Frequency This is the inverse of the period = 1/T or the number of repititons of the period per second, it is expressed in cycles per second or Hertz (Hz). The Results of this experiment are documented overleaf.
Conclusion In conclusion, this experiment helped to familiarise me with the use of an Oscilloscope, a test meter, a waveform generator and a spectrum analyser. The experiment also helped in enhancing my understanding of terms such as, frequency, Spectral lines, R.M.S. and Peak-to-Peak voltages. All aspects of this experiment went smoothly and without problems, although we did struggle at one stage when we believed the analyser to have frozen, but this was as a result of forgetting to release the pause button on the machine which is used for freezing a recording.
Things every student should keep in mind
- Free example essays found anywhere online are available to anyone, which makes them used, re-used, paraphrased, and abused millions of times.
- Watch out, some are poorly written!
- We strongly discourage you to submit free essays or any of their parts for credit at your school -- they are easily detected by PLAGIARISM CHECKERS.
- Get a brand-new, 100% original paper that will be written especially for you following YOUR EXACT instructions.
100% money back, no questions asked if you paper is plagiarized (this won't happen anyway).
We use a simple but effective principle: one satisfied customer will come back for more, but one who was cheated and misled will tell 10 others too.

I am an ESL student and I am only learning how to write good papers in English. Thanks to EssayPride I am mastering this skill much faster. They help me because they always respond any questions and explain me things I do not understand. They also strictly follow the deadlines and I am never late with my assignments. Thank you very much, guys, your hard work is appreciated. I will surely be ordering more.

Oh my Gosh! My life has become sooo much easier after I've come across this website. I am a working student, so sometimes I am too overwhelmed with so many things and I really need a hand with my papers. I am glad I have found a company I can trust. I have confidence in these guys, because they proved to be good quite a few times.
Kirk N.

I never leave reviews for products or services because I am quite particular and picky. Surprisingly enough, EssayPride has managed to satisfy all of my requirements, even though I asked for several alterations to the paper they've sent initially. My assignments are quite complicated and it is essential to possess a certain level of knowledge in order to write a decent paper. These guys have managed, so I give them four stars.

I am a Korean student studying in the US. I would like to thank essaypride staff, especially writer Jeff P., for helping me out so much. My grades are good with all your help and I keep calm about the results of my year.

As probably any student, I was quite hesitant about asking somebody else to do my assignments at first. However, after EssayPride has sent me my first paper and I've read it, I understood that I could actually learn a lot from them. The research they've done was impressive and I understood the topic even better than after going to class and reading my textbook. I am not using this website to "cheat", I am using it as a tutoring service, they help me to understand the material better.
