FFT Analyzer In applications such as rotating machinery monitoring, structural analysis, and durability testing, the FFT analyzer plays a central role in extracting key information from measured signals. The FFT analyzer provides real-time spectrum analysis on an unlimited number of channels, with resolution up to tens of thousands of lines. DEWE VIETNAM delivers this capability as an integrated measurement system, tightly connecting DAQ hardware, sensors, and analysis software to meet demanding frequency analysis requirements—from laboratory testing to long-term industrial monitoring.
