New options enhance functions on power analyser
New voltage fluctuation/flicker and cycle-by-cycle options have been introduced for the Yokogawa WT3000 3-phase precision power analyser, further enhancing the superb product functionality
In the IEC harmonic measurement mode, the instrument can be used with the new Yokogawa 761922 harmonic measurement software to perform tests conforming to IEC 61000-3-2 rev2.2.
It complies with the latest IEC61000-3-2 and IEC61000-4-7 requirements, including 10/12 cycle waves at 50/60Hz, inter-harmonic measurements and grouping.
The wide-bandwidth harmonic measurement function allows harmonic analysis on waveforms with a fundamental frequency range from 0.1Hz to 1kHz (or 0.1-10Hz using an external sampling clock).

Next-generation wideband modulation analyser
The new VN7100 wideband modulation analyser features a maximum analysis bandwidth of 168 MHz, the world's highest for this product class, making it ideally suited to the next generation of LAN systems
Measurements can be made up to the 50th-order harmonic at a 1kHz fundamental frequency, or up to the 20th-order harmonic in the range from 1.1kHz to 2.6kHz.
Two FFT calculations can be performed simultaneously on waveform data of measured voltage and current, with a user-selectable minimum resolution of 1Hz or 10Hz.
FFT analysis can be performed at up to 100kHz.
Up to two waveform calculations and other mathematical functions can be carried out at once.
With a formula that multiplies voltage and current waveforms, an instantaneous power waveform can be performed on screen.
Mathematical data can be saved in CSV or WVF format, and WVF data can be displayed on the Yokogawa WTViewer application software 760122 and saved in CSV format.
The transient waveform storage function enables waveform quality to be precisely analysed.
All captured voltage and current waveform data up to the maximum sampling speed 200kS/s, along with waveforms calculated using the mathematical and FFT functions, can be stored into the acquisition memory, which has a maximum capacity of 48M points.
The stored data can be saved in CSV or WVF format into PC card or USB memory, and easily transferred to PC via USB, Ethernet or GP-IB interfaces.
The Yokogawa WT3000 precision power analyser provides 'best in class' precision and stability.
With a basic power accuracy of +/-0.02% of reading, DC and 0.1Hz-1MHz measurement bandwidth, and up to four input elements, the WT3000 provides a high-accuracy measurement solution for testing all types of power electronics products.
