The diploma thesis deals with upgrading of the existing automated test bench with a new power analyzer PPA5530. The adjustment of programs in LabVIEW software environment is described and the measurements are presented.
In the first part of the thesis all the components which were used for upgrading are described, the main components being the PPA5530 and NORMA D6000 power analyzers, the NI PCI-6251 board and the SCB-68 I/O connector block. There are also some information on how the automated test bench works.
Further on, the programs that were developed and added into the existing software of the test bench are described. It was necessary to develop a software which enabled the communication of LabVIEW software environment (installed on a personal computer) with the new PPA5530 instrument through three different communication protocols – GPIB, USB and ETHERNET.
In addition, another software was developed – this software enables to carry out comparative measurements between the new PPA5530 instrument and its predecessor NORMA D6000. A software that generates test PWM voltage signals, which were used for comparing the mentioned systems, is also described.
In the final part of the thesis the results of comparative measurements are shown and commented.
