Grid dip meter with large-diameter measuring coil
Obr, Michal ; Koton, Jaroslav (referee) ; Hanák, Pavel (advisor)
This master’s thesis deals with grid dip meter, its operating principle, characteristics and with measuring procedure. The thesis contains basic division of oscilators, its characteristics and operating principal. The master`s thesis contains complete design of grid dip meter with large-diameter measuring coil which is placed outside the device. Grip dip meter is made of SMD components on a one-sided printed wiring. Grip dip meter consist of transformer itself, that has two secondary windings as a supply for resonance meters and internal digital frequency meter. The device has analog panel gauge and BNC input for extrenal counter.

Tester amplifier for high impedance speaker measurements
Obr, Michal ; Mišurec, Jiří (referee) ; Káňa, Ladislav (advisor)
The presented paper deals with the basic division of amplifiers by their properties and a design of an amplifier with LME 49810 exciter with low output performance intended for measuring high-impedance speakers on a 100V link. This specific design contains basic safety components for secure function of the amplifier and connected speaker. The amplifier includes a digital gauge to measure output RMS voltage.
