Résumé
In this work is analysis of methods for measuring high-frequency power, then the design and implementation of multi-channel processor controlled high-frequency power meter. The device enables communication via USB or RS232 port, correction and calibration calculations stored on the SD card. Measurement results are displayed on the LCD display. The meter has three probes whitch can measure up to 8 GHz. Built-in 40 dB attenuator allows measure with power up to 100 W. A complete functional test tool including three types of probes, measuring unit and software.
