The new FireWorks 1394 VK9000 from Yokogawa Martron is designed to provide engineers with a powerful 'out of the box' solution for testing systems based on the IEEE-1394 bus.
Bluetooth analysis via the USB
At the Embedded Systems Show Yokogawa Martron is introducing a new Bluetooth analyser to complement its range of test and measurement tools for communications and bus protocol analysis.
In the IEC harmonic measurement mode, the instrument can be used with Yokogawa's new 761922 harmonic measurement software to perform tests conforming to IEC61000-3-2 Rev 2.2.
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).

Two-channel digital scope claims breakthrough
Yokogawa is claiming a price/performance breakthrough with the addition of a new two-channel instrument to its SignalExplorer family of compact digital oscilloscopes.
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 1.1 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 1 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 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 200Ksample/s, along with waveforms calculated using the mathematical and FFT functions, can be stored into the acquisition memory, which has a maximum capacity of 48 million 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 GPIB interfaces.
The Yokogawa WT3000 precision power analyser claims "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.
