Precision power analyser enhanced by input module
Yokogawa Europe has enhanced the WT3000 precision power analyser with a 2A current input module to provide highly accurate measurement of electronic products.
The wide-bandwidth harmonic measurement function allows harmonic analysis on waveforms with a fundamental frequency range from 0.1 Hz to 1 kHz (or 0.1-10 Hz using an external sampling clock).
Measurements can be made up to the 50th-order harmonic at a 1 kHz fundamental frequency, or up to the 20th-order harmonic in the range from 1.1 kHz to 2.6 kHz.
Two FFT calculations can be performed simultaneously on waveform data of measured voltage and current, with a user-selectable minimum resolution of 1 Hz or 10 Hz.
FFT analysis can be performed at up to 100 kHz.
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 Yokogawa's 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 0.1 Hz-1 MHz measurement bandwidth, and up to four input elements, the WT3000 provides a high-accuracy measurement solution for testing all types of power electronics products.
