Abstract :
Our RF signal-quality measurement macro employs 1) the new window-shifting measurement technique, which can obtain power of high-frequency component with lower-frequency measurements, and 2) the new stair-like weighted addition technique, which can decrease the error due to harmonic power of measured signals. The macro was only 1/10 area of conventional spectrum analyzers. Carrier power of 2.4 GHz-Tx with the measurement error of <1dB was measured without RF-testers, and harmonic-emission exceeding FCC regulations (>-20dBm) were successfully detected.
