Objectives
Programme
1. BTO
During the first one-hour lab session, in addition to discussing mid-semester tasks and lab assignments, students participate in accident and fire prevention training, which is confirmed by signing the attendance sheet.
2. EPH
Pipeline measurements to demonstrate a distributed parameter network, traveling and reflected wave, resulting field strength distribution; definition and measurement of voltage reflection factor, standing wave ratio.
3. ANT
Presentation of antenna measuring room. Practical confirmation of basic antenna concepts, measurement of input impedance, gain, directional characteristics.
4. MH
Examination of the solar power supply system of CUBESAT-type pico-satellites, U/I/P characteristics of the solar panel, tracking and power transmission efficiency of the solar panel matching circuit /MPPT/, energy storage, solar panel matching, etc.
5. LMP
Testing of the hardware components of the satellite on-board plasma diagnostic instrument, as well as the functional examination of the complete equipment, the analysis of the data traffic and the operation of the CAN bus.
6. FSK
Examination of the typical properties of the FSK transmission system operating in ISM bands, study of typical circuit solutions on two-chip (transmitter and receiver) circuits, overview of the antenna types used.
7. RMD
Conducting and evaluating micro-Doppler measurements with active radar. The objects to be examined: hang glider, walking man, drone. During the evaluation, the main parameters of each movement are determined.
8. KSM
Simulation examination of extended spectrum modulations, then measurement of the same modulations and the corresponding matched filters. Modulations: BPSK and QPSK.
9. ZZZ
Antenna digital beamforming measurement. Receiver antenna line measurement. As a first step, we determine the vectors h for the antenna characteristics facing in given directions, and then check this with simulation. Finally, the array of antennas available for measurement is programmed with the vectors h and the directional characteristics are checked by measurement.
10. CsM Mobile radio channel simulation test in MATLAB environment; channel models to handle the effect of various noises and fadings in the case of a moving reception point. Effect of weather parameters on wave propagation; the students analyze the effect of atmospheric meteorological phenomena in radio links based on the weather and section attenuation data of the microwave connections operated with the cooperation of the research group of the V1/215 lab.
The purpose of the subject is to support and supplement the theoretical knowledge taught in foundational and specialized subjects with practical knowledge, by solving calculation and measurement tasks.

Oktatási módszertan
The laboratory measurements take place in the student and research laboratories of HVT in the form of 4 hours laboratory exercises. At the beginning of the semester, all students take part in the accident and fire prevention briefing and then complete the measurement exercises related to the listed topics.
The measurements take place in measurement groups of 2-3 people according to the department's schedule. The preparation for the measurements is based on the aids shared on the official website of the subject faculty. The preparation is checked at the beginning of the measurements based on the questions in the aids. If it is not appropriate, the student will be instructed to take a supplementary measurement.
The completion of the measurement is confirmed by the signature of the measuring supervisor in the position at the measuring site. The participants submit 1 measurement report for each measurement group to the measurement manager electronically.

General rules
Requirements:
In order to be recognized for the semester, participation in the laboratory
presentations, as well as the completion of the measurements certified by the
supervisors' signature - during the teaching period (or during the supplement week) -
and at least a sufficient grade for each measurement are required.
The end-of-semester mark is based on the grades received for the individual
measurements according to the rounded average.
The condition for starting the measurement is min. 60% completion of the entrance
exam consisting of 5 control questions.
Evaluation of individual measurements:
The basic grade for the completion of the mandatory tasks: medium (3)
Factors that improve the grade:
Completion of optional tasks: +1 mark
Evaluation of the results: +1 mark
Factors affecting the grade:
Two incorrect answers to the verification questions: -1 mark
Missing or incorrect measurement results: -1 mark
Additional possibilities:
It is possible to suplement a maximum of 2 measurements only during the teaching period (or during the supplement week), at a time agreed in advance with the measurement leader.
