Furthermore, the PW6001 offers harmonic analysis up to 1.5 MHz as a standard feature. This wideband harmonic analysis supports up to the 100th order for fundamental frequencies from 0.1 Hz to 300 kHz. This capability is essential for understanding power quality issues, assessing the impact of non-linear loads, and diagnosing problems in modern power systems. It enables accurate analysis of fundamental waves in motors and precise measurement of distortion rate in the transmission waveforms for wireless power supplies. In addition, the PW6001 supports FFT analysis of target waveforms, allowing for frequency analysis up to 2 MHz. Users can specify any waveform analysis range to identify and display the 10 highest peak values and frequencies. This powerful spectral analysis helps in identifying resonant frequencies, noise sources, and the frequency components of complex signals. The instrument also includes a Digital LPF (Low-Pass Filter) for displaying the waveform you want to view. Users can select a specific cutoff frequency, and the digital LPF greatly reduces unwanted noise, ensuring that the displayed waveform provides clear and relevant information. This comprehensive array of analysis functions makes the PW6001 an indispensable tool for advanced research, development, and troubleshooting in highly dynamic and complex electrical systems.
