Automated station for DC and AC measurements
Burian, Josef ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
he object of this work is the suggestion of workplace for measurement of direct-current and alternating current quantities. This work is divided into several basic units. There are described separate elements of the workplace by the HW over the bus line up to the SW in full details. The selection of HW and the suggestion of service program is approached in the next part. To the program creation was used environment for virtual instrumentation VEE 9.2 made by Agilent company. Resulting program is described in this work in full details. The last part of this work concerns with test measurement and valuation of the whole work.

Communication module for power supplies controlling
Zachar, Jiří ; Šmíd, Petr (referee) ; Dřínovský, Jiří (advisor)
The aim of this work is to design a communication module for laboratory source Manson. This power supply communicates only through a serial RS-232 link. Modern computers usually use for the connection with other peripherals mainly USB. Designed communication module contains converter between the RS-232 and USB. Power supply is used in the automated measurement setup, which is controlled from the Virtual Engineering Environment from the Agilent Technologies. Direct commands for laboratory source Manson are not compatible with the SCPI (Standard Commands for Programmable Instruments) standard commands. So, the communication module converts commands from the SCPI format to Manson supply instructions. The communication with the Manson supply will be obvious for students by using new communication module.

Basic measurement of bipolar and unipolar transistor
Kaňa, Leoš ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
In terms of the better effectiveness in the sphere of transistor characteristics measuring, no matter unipolar (FET) or bipolar (BJT), in laboratory conditions and their better understanding in terms of thrash out a subject matter is desirable have to available workplace let us say preparation enabling this kind of measuring with modifiability wiring and with possibility to change measured component. This thesis isn‘t focused only on development of this kind of universal component for measuring but simultaneously contains brief summary about the theory and parameters of transistors. Next aim is the development and realisation of static characteristic measuring program in VEE 8.0 Pro environment. Finally the complex laboratory exercise has to be done for measuring of bipolar and unipolar transistor’s static characteristics include programs for automatic measuring. For developing of DPS was used developing system named Eagle which gives us instrument with sufficiently accuracy. In thesis is contained theory needed for measuring and programming. Except possibility of measured component change we can change transistor connection in circuit on the board. This change is available for BJT (CE, CB, CC) and unipolar JFET (CS, CG, CD) transistor’s.

Computerized measurement of characteristics of analogue functional blocks
Pšeno, Daniel ; Urbanec, Tomáš (referee) ; Brančík, Lubomír (advisor)
Aims of this bachelor`s thesis were design laboratory appliance with controlled sources and programming in graphic development software VEE by Agilent. The appliance will be including all four types of controlled sources. It will be applied on place of computerized measurement system in laboratory of Analogue electronic circuits. Program will be working with all of measurement devices on work place. PC is connected to all measurement devices by GPIB bus. In the first part of this project is talked about computerized measurement system work place, graphic development software, about programming of devices and designed four programs in VEE. In the second part of this project are included simulations of all types of controlled sources in software PSpice. Optimal ratio constants are set up by the simulation output. Printed circuit board is designed in Eagle software.
