Wide Bandwidth Harmonic Measurement Mode
Harmonic measurement for a frequency range of 0.1 Hz – 2.6 kHz
Enables harmonic measurement over wide bandwidths. Supports measure-ment of harmonic signals beyond those of the harmonic measurement func-tion in normal measurement mode. This option allows for harmonic analysis on waveforms with a fundamental frequency range of 0.1 Hz–2.6 kHz (*1). You can measure up to the 50th order harmonic at 1 kHz fundamental.(*2).
*1 0.1–10 Hz using an external sampling clock.
*2 Harmonic measurement of up to the 20th order possible in the 1 kHz to 2.6 kHz range.
Harmonic Measurement Function
Same as harmonic Measurement Function /G5
This function enables simultaneous measurement of normal and harmonic data, which was impossible with previous Yokogawa models. Since with the WT3000 you can simultaneously confirm total voltage and current as well as the distortion factor and fundamental wave without switching modes, this allows for more accurate and efficient measurement of the power supply quality, the fundamental wave of motor drive voltage, and other factors.
IEC Harmonic Measurement Mode
Can perform tests conforming to international standards.
The IEC harmonic measurement mode meets the window width requirement of the latest IEC harmonic standard (10 cycles of 50 Hz and 12 cycles of 60 Hz). Also, this mode allows users to use the
761922 harmonic measurement software to perform tests conforming to IEC 61000-3-2 and IEC61000-3-12.
* These modes cannot be used at the same time.
FFT Calculation Mode
More detailed frequency analysis than with the harmonic measurement mode.
Two FFT calculations can be performed simultaneously on waveform data of measured voltage and current. You can select a resolution for FFT of 1 Hz or 10 Hz. FFT analysis of up to 100 kHz can be performed.
Waveform Calculation Mode
Monitoring of instantaneous power waveforms.
Up to two waveform calculations and other Waveform Calculation functions can be used at once. If you create a formula that multiplies voltage and current waveforms, you can confirm an instantaneous power waveform on screen. Waveform Calculation data can be saved in CSV or WVF format.
Waveform Sampling Data Saving Function
Saving of detailed waveform data for confirmation.
All captured voltage and current waveform data (200 kS/s), calculated wave-forms, and FFT calculated waveforms can be saved. You can choose to save in CSV or WVF format, and to save to PC card or USB memory (/C5 option).
