With a sampling frequency of 3.84MHz and a 14-bit A/D converter, it achieves an FFT range of 1.5MHz and a dynamic range of 85dB.
A SYNC cable allows for synchronized recording from up to four cameras.
By adopting IEEE1394, stable high-speed data transfer is achieved.
In addition to the dedicated data processing software for the AU-0402, high-performance analysis is possible using the XN-8100 Repolizer and LV-0910 vibration analysis software, as well as time-series data analysis using Oscope Professional.
The AU-4300 high-speed sampling unit is an A/D unit capable of accurately measuring frequencies from over 100 kHz up to 1.5 MHz. Until now, objects requiring high-speed vibration measurement, such as ultrasonic equipment, tools, vibration elements, and MEMS, required digital oscilloscopes or expensive signal analysis systems. While these instruments are advantageous for time-domain observation due to their high-speed sampling, they were unsatisfactory in terms of resolution and dynamic range for frequency analysis. Ono Sokki has developed the AU-4300, a well-balanced high-speed sampling unit for frequency analysis in this frequency range, featuring 3.84 MHz sampling (FFT analysis range = 1.5 MHz), a 14-bit A/D converter, and performance with amplitude flatness of ±0.5 dB, inter-channel phase accuracy of ±5 deg, and a dynamic range of 85 dB typ. Compatible software includes the simultaneously released dedicated data recording software AU-0402, as well as the signal processing software "XN-8100 series Repolyzer2," the vibration analysis software LV-0910, and the offline time-series data analysis tool "Oscope Professional."
