Tiedotuksia / Bulletin board

All info here is in English, with random parts translated into Finnish as well. So never mind the Finnish if you can't read it.

  • Antenna lab reports have been graded. See the results here. Pick up yours from Tiiti, SM301 (even if you did not get a boomerang). Tiiti promises to be in: Monday: 9-1015, 1230-1630; Tuesday: 9-1030, 12-1330; Wednesday: 9-1130, 1230-1630. Return your corrections by Tuesday, Feb 21, to Tiiti or course mailbox. (Feb 13)
  • See the photos from the only successful antenna measurement from last week. Thanks to Ellu and Karkki for the pictures. Btw, Satimo suffers from a broken PA (power amplifier) and will be repaired shortly. (Feb 1)
  • Reserve your oral examination time in Doodle! Make the reservation by Wed, Feb 15. If you cannot find a time slot, contact Tiiti well in advance!
  • Oral exam: You will be given a data sheet and an exam sheet. You have 30 minutes to prepare on your own. Then you will be called to the RF laboratory to make some measurements and to explain your choices. You have 60 minutes in the RF laboratory, so 1.5 hours in total. You are allowed to use material or ask the examiner, but you will not have much time to study books in the exam. Exam times (Feb 20-24) will be posted on Doodle next week. (Jan 18)
  • EMC chamber measurement results and measurement notes can be found on the Antenna lab page, see "Laboratory task" section. (Jan 11)
  • See the course grading: how the lab report grades affect your final grade. (Nov 15)
  • Subscribe to the course mailing list! Send mail to majordomo@ele.tut.fi, and write 'subscribe rf-mittaus' in the message body. To unsubscribe, write 'unsubscribe rf-mittaus' in the body. Send mail to the list to rf-mittaus@ele.tut.fi. Make sure you send the emails from inside *.tut.fi.

Self-practice: You may go to the RF laboratory to practice on your own. Completely voluntary. No guidance is provided. Contact Tiiti if you don't have the access rights, she will then let you in.

Laboratory Work

The course includes three laboratory tasks: spectrum analyser, vector network analyser, and antenna tasks. You will complete each with your workgroup (pair). Good laboratory reports may benefit in better grades.

Included in the lab task:

  • Reserve a time slot for the lab task. You will work with the same labmate throughout the course.
  • Prepare a pre-task according to the instructions. Answer the questions and plan the measurements. Bring the pre-task to the lab.
  • Make the measurements in the laboratory. The lab assistant will guide you, and there will be more detailed instructions available.
  • Write a post-task report. The report should resemble a scientific paper or a paper that you would give to your boss. Follow the instructions. Staple the pre-task, the measurement notes, and the post-task together and leave it in the course red mailbox in SM2.
  • Send a personal report by e-mail to Tiiti, commenting on what you learned and a self-evaluation.
  • In case there is something to fix, a boomerang is given, and you will have one week to make the corrections.
  • P.S. 75% of the grade comes from lab reports. Try your best!

Detailed pre-and post-task instructions for each lab are on separate pages:

Reserve your antenna lab time in Doodle! Make the reservation by Fri, Jan 20. One pair at a time, one time for each pair. If you cannot find a suitable time slot, contact Tiiti.

Additionally, you are allowed to go independently to the RF laboratory to practice on your own. This is indicated as self-practice in the course contents. Contact Tiiti and she will let you in. Note: if you have the access rights because of the RF Project course, you can just go.
